Publisher's Summary

A dangerous serum. A deadly enemy. A suffocating secret.  

I didn’t know it was possible to be in love with two people at the same time, until my past and present collided. 

Jensen was unpredictable and compelling, until he shattered my heart when he was deployed.

Trent is loving and dependable, and I can easily envision a future in his arms.

I had no way to know the two were brothers. I fear I will be what tears them apart. 

When Trent is deployed to Afghanistan to test a highly classified serum, I can’t shake the feeling of dread. My fears are quickly justified. An unknown enemy knows my dark secret and plans to use it against us.

I made a mistake once, and now it could destroy everyone I love.

WHAT THRILLING COCKTAIL.. IT BLEW MY MIND

Wow, what a unique, edgy and compelling journey.. the characters suck you in and the storyline explodes into a suspenseful, tension-filled and emotionally complex rollercoaster. This is not a heroine in a plain ‘either or’ situation whose torn between two brothers story. Skyla first meets kind, caring, drool-worthy Jensen first and, for ten days, they have a blissful relationship but the sexy Marine gets deployed to Afghanistan for six months and, selflessly, doesn’t want Skyla to have to put her life on hold so he ends things. Fast-forward three months and Skyla meets Trent.. a wonderful, caring, sexy, understanding Marine.. but Skyla would later learn he’s Jensen’s brother. She’s had to move on from Jensen and, for three years, Trent has been hers. Trent and Jensen are best buds but Trent is unaware of their secret past history.. it’s an emotional powder keg waiting to blow.

An experimental serum which changes a soldier’s emotions in combat.. Trent is the person in charge of the highly classified serum. The serum is the fuse that will bring catastrophic consequences for everyone. And a father’s revenge and hatred will be the match that lights the fuse.. and boom.. disaster, heartache, epic suspense, chills, manipulation, deadly dilemmas, dark hours with no way out and much.. much.. MUUUUCH more.

Worth a credit? Skilfully weaved, masterfully crafted and awesomely narrated from three different POVs by A list narrators who turn a great Book into an unforgettable listen. Your heart warms, jumps, hardens, softens, shatters, gets shredded and pounds so fast you consider dialling 911. It breaks with the shocking twisted brutality, the betrayals and the desperate anguish and it eventually slows to a normal beat and melts with all the swoony feels in this epically emotional story of love and hate. The great narration.. the brilliant and uniquely different edge-of-your-seat storyline.. the strong heroine, the worthy heroes and the swoons, tears, twists, conflicts and deep love definitely make this an unforgettable, and yes creditworthy, listen.

Talk about an emotional roller coaster!

Wow. This one took me on a ride. Up and down. In and out. But every moment was incredible. Ryleigh is an epic world builder. The love triangle. The emotions. The suspense. I hung on every word and in the end I cried happy tears. The casting was over the top amazing. Each perfect for their role. Thank you Ryleigh for yet another amazing journey!!

Oh Holy... WOW!!!

I can't find the words to express my feelings for this book or even the words to describe this book. The only word that comes to mind is, "Wow".

Having gone into this book completely blind I had no idea what I was getting myself into. I thought I was going to get a sweet romance about a girl who was having a hard time choosing between brothers... Oh no. I got the opposite and in a delicious way. It's a story about a dangerous serum and a love triangle that leads to loss and betrayal.

Don't let the idea of an emotional rollercoaster scare you away from this one. It is worth all the emotions.

Audio Review: I listened to this one and let me tell you, the performances of Jason Clarke, Aaron Shedlock, and Kylie Stewart added another edge and more emotions than if you were to read it yourself. Aaron and Kylie were fantastic on this audio. I could go on and on about these two. But Jason... oh boy. This has to be his best audiobook to date. It is definitely a favorite of mine by him, Aaron, and Kylie. 100% recommend this audiobook.

Don´t forget to Breathe! Awesome story & narration

Oh my god! Where to start! I had to tell myself to breathe a few times as there was so much anxiety and suspense in this book that I kept holding my breath and forgot to exhale. I frequently thought, ok, the storyline is giving me a break but then bam another blow. This dark edge of your seat-worthy romantic suspense combined with thrilling angst sends you on a deep emotionally filled rollercoaster. My heart was racing and crying out at the same time! There are so many feelings and so much I want to say but I try to keep it shortish.

Rayleigh Sloan broke me, oh did this story ever pull on my heartstrings and yes there were tears! My feelings swayed from sad, to anger to right out loathing towards some characters. Her words were torture to my heart and soul but in the best possible way. There are totally swoon-worthy moments in this story too. I loved what the author did with this story. Seriously what a damn good book, brilliant storyline, engaging characters and heart-gripping entertainment with an ALL.THE.FEELS cast of perfect voices who brought this incredible military love triangle to life!
Speaking of love triangles, I never really know how the author is going to untangle the situation but this one was so well done! I am still stupefied by how this story developed and was wrapped up.

This story is about Skyla who is emotionally connected to two men, brothers, Trent & Jensen, and captured by the feelings she has for each one. A series of unexpected and shocking events are turning their life´s upside down and re-shuffling everything. It shows how grief & emotional torture can make people do unspeakable things specially enhanced with experimental drugs. It really is the dark side of chemistry no matter if this chemistry is born out of love or a serum.

The story is told in 3 different POV´s by Kylie Stewart = Skyla, Jason Clarke = Jenson & Aaron Shedlock = Trent. All three narrators get the highest praise as the performance was simply stunning, emotional, and believable. The setting, the mood, the feelings they conveyed. Perfection all-round!

** Edgy, Emotional and Evocative **

Ryleigh Sloan leaves you sitting on the edge of seat right through to the very end! The twists and turns just keep on coming.
The evocative and emotional performances of Jason Clarke, Kylie Stewart and Aaron Shedlock are the icing on the cake.
A great read for lovers of suspenseful, military romance, and/or love triangles.

Well done and gripping

I already enjoyed this author’s work in another genre, so I was curious about reading some romantic suspense by her. I was blown away.

Though a bit unrealistic–such a level of mind control is still an illusion–the mystery plot is still well done and gripping. I really enjoyed how the personal story of the characters mixed with the bigger spy story.

I’m a sucker for a good love triangle. The one where you’re never sure who’s gonna be chosen because there are deep feelings everywhere. This book has one of those. The brotherly love between Jensen and Trent, tainted with the secret between J and Skyla, made the conflicts between them even more emotional. I’d have loved to see more of Skyla and Jensen’s past relationship though–one single flashback and some reminiscence from the characters felt not enough to understand the depth of their feelings for each other. As for Skyla’s relationship with Trent, we see but a glimpse of it since they’re quickly separated–but since it’s a long term relationship, it was easier to see the love between them. Still, that’s one powerful love triangle that kept me on edge until the very end.

The handful of villains who threatened them, despite clear motivations–that I guessed pretty fast–didn’t feel real. More like cartoon villains. Except for one unexpected one. But I won’t spoil the surprise. This one, though, made the whole story more painful to read. Oh, the angst!

And the narration? I wasn’t sold on the female narrator, to be honest. But the two male narrators were perfectly cast. The one doing Trent was especially great with the character. They brought life to those three tortured characters in their search for happiness. A very good listen.

Absolutely Brilliant! Phenomenal Story &Narration🎧

This book is absolutely amazing, it took me a while to get my thoughts together because the mind-blowing story left me speechless and I could not possibly find the right words to give it the praise it deserves. I think the less you know going in the better so I will be vague with details in my review, just know this is no ordinary romantic suspense it is so much more. It is best to go in knowing little and just hold on tight and enjoy the ride. The story drew me in right from the start, it did not just captivate my attention it held it hostage, this is one of the books that you can not put down because you need to know what happens next. Ryleigh Sloan is a gifted author with a brilliant mind and a wonderful writing style, the storylines and characters she created are interesting, original and complex, they are also realistic, easy to relate to and connect with. The descriptive details are fantastic, they bring you in to the story, right along side the characters giving you an inside view of everything they see, think and experience. The book starts out with Skyla and Trent, they’ve been together for three years and their relationship and love is rock solid. Trent works with her dad, a Colonel in the marines, they have been working on a serum that could help soldiers in combat situations and are conducting a study. Trent gets deployed to work with soldiers in the field, one of those soldiers is his brother Jensen. Skyla had met Jensen before Trent, they shared a special time together but he did not want to start anything because he was deploying overseas and did not know when he would be back. He never stopped thinking about her, it was the same for her but after months of moping around she decided to move on and that is when she met Trent, not knowing he was Jensen’s brother. Skyla opted to keep that information from Trent, Jensen went along with it but it left him with a lot of animosity and angst. When their mission in Afghanistan turns into chaos, Trent winds up injured and the mission is halted and they return home. After his return all their lives are turned upside down. I am still in awe of everything that happened this book, the story is cleverly plotted with plenty of drama, angst, mystery, action, twists and turns, thrilling suspense that not only took me to the edge of my seat but had my heart pounding so hard I felt like it was going to jump out of my chest, heartfelt emotions and some hot romance. Ryleigh Sloan, thank you for this amazing story and the thrilling and emotional rollercoaster ride.

🎧📚🎧 Ryleigh Sloan could not have chosen a better cast to bring her characters and their story to life. Jason Clarke, Aaron Shedlock and Kylie Stewart are fabulously talented voice artists, they had a complete understanding of the roles they were playing, took that role and made it their own sounding believable and just as I pictured them to sound. Aaron Shedlock played Trent brilliantly, grasped his persona in each scenario with perfection, Jason Clarke’s Jansen was amazing as well, performed every single one of his emotions and made you feel them. Kylie Stewart’s Skyla shone like the star she was, she captured her strength as well as her vulnerable moments. These three entertaining storytellers delivered an outstanding performance, a performance that enhances an already brilliant story another level. Thank you for this amazing listen!
