It’s been years since 17-year-old Becca Hart believed in true love. But when her former best friend teases her for not having had a boyfriend, Becca impulsively pretends she’s been secretly seeing someone. Brett Wells has it all.

Yet, somehow, Wes and Michael are hitting it off, which means Wes is Liz’s in.

Hi, my name is Bree Camden, and I’m hopelessly in love with my best friend and star quarterback Nathan Donelson (so is half of America, judging by the tabloids and how much the guy dates). The first step is admitting it, right? Except, I can never admit it to him because he clearly doesn’t see me that way, and the last thing I want is for things to get weird between us. Nothing but good old-fashioned no-touching-the-sexiest-man-alive platonic friendship for us! Everything is exactly how I like it! Yes. Good. (I’m not crying; I’m just peeling an onion.)

Kailyn Flowers was always calm, rational, and controlled - until she ended up sprawled all over Daxton Hughes, the former actor she totally crushed on as a teenager. Then she did the unthinkable: She became a mortifying fangirl in five seconds flat, which may or may not have included professing her undying love. And oddly, he didn't run away. In fact, their meet cute led to a friendship she never saw coming. Of course, she never saw his betrayal coming, either....

Barrett Bloom is hoping college will be a fresh start after a messy high school experience. But when school begins on September 21, everything goes wrong. She’s humiliated by the know-it-all in her physics class, she botches her interview for the college paper, and at a party that night, she accidentally sets a frat on fire.

Lucy Hutton has always been certain that the nice girl can get the corner office. She's charming and accommodating and prides herself on being loved by everyone at Bexley & Gamin. Everyone except for coldly efficient, impeccably attired, physically intimidating Joshua Templeman. And the feeling is mutual. Trapped in a shared office together 40 (ok, 50 or 60) hours a week, they've become entrenched in an addictive, ridiculous never-ending game of one-upmanship.

I don’t usually go for tattoo-covered, video-gaming, hockey-playing nerd-jocks who think I’m flighty and superficial. His narrow view of me is the first strike against him. It doesn’t help that he’s buddy-buddy with my brother. And that his best friend has a crush on me. And that I just moved in with them. Oh, did I not mention we’re roommates?

Leon, a night shift worker, will take the apartment during the day, and Tiffy can have it nights and weekends. He'll only ever be there when she's at the office. In fact, they'll never even have to meet.

Single mom Jess Davis is a data and statistics wizard, but no amount of number crunching can convince her to step back into the dating world. After all, her father was never around, her hard-partying mother disappeared when she was six, and her ex decided he wasn’t “father material” before her daughter was even born. Jess holds her loved ones close but working constantly to stay afloat is hard...and lonely.

She's a tomboy. He's the boy next door. With three older brothers, Charlotte Reynolds, aka Charlie, has always been more comfortable calling the shots on a basketball court than flirting with the opposite sex.

Camilla dreams of the day she can leave her life behind.

After that dark night on the beach, Graham confessed, the case was closed, and Jill tried to move on.

Other times, only a night with a stranger will soothe the pain. On the night Isaac and I met, we tried all three. When it was over, we went our separate ways. We planned to never see each other again, but I should really know by now that plans don’t work out the way they're supposed to. 

Morgan, an elite track athlete, is forced to transfer high schools late in her senior year after it turns out being queer is against her private Catholic school's code of conduct. There, she meets Ruby, who has two hobbies: tinkering with her baby blue 1970 Ford Torino and competing in local beauty pageants, the latter to live out the dreams of her overbearing mother.

Lock is awkward. He can't make eye contact, counts when he's nervous, and has to remind himself several times a day how "normal" teens behave.

He's an actor. He can act normal. But then there's Lock. 

Secretly hooking up with the team captain's sister was a bad idea. In my defense, the first time I saw her I didn't know who she was. Kind, gorgeous, a little naïve. Ginny brightened my world from day one. I knew I was no good for her. She was just out of a relationship, and I had a reputation for having a new girl in my bed every weekend. I tried to do the right thing. Honest. I'm the one who insisted we should be just friends. That lasted about as long as you'd expect. But Ginny? She's the best - best friend, best everything.

We knew each other once upon a time, but even if I’m named after a princess, it doesn’t mean my life is a fairy tale. My plan is to keep my head down, get my degree, and leave this town. But the moment Mascen Wade recognizes me, all my carefully laid plans come crumbling down. He’s decided he wants to make my life a living hell, but I’m not so easy to push around. 

I knew something was wrong the second she walked in the door tonight; I just couldn't put my finger on what it was. Same hair color. Same legs. Same face. Except...I look harder. At the small dimple beneath her lip that wasn't there the last time we went out. And her laugh - that laugh isn't as loud. This isn't the girl I've gone out with the past few weeks. It's her twin sister, and they've switched places on me.

His family's life revolves around the church, a church run by the vocally intolerant Pastor Myers, so Mike has resolved to spend his life in the closet.

A sketchbook he carries everywhere. When his sketchbook goes missing in the middle of Sunday school, Mike is sure his life is over.
