The Misconception: A Spirit Guide, A Ghost Tiger, and One Scary Mother! Publisher's Summary
Megan is a 12-year-old girl with supernatural powers. Some of them are still only partially developed and others are working, but she doesn't know how to use them yet.
Her biggest problems for the moment is finding a teacher who can show her how to use them properly. Another is that she doesn't know anyone who knows anything about supernatural powers. In fact, her mother is violently against the supernatural, as was her mother before her.
The only people who seem willing to help her are dead, not that that makes any difference to Megan. She embraces their help with open arms.
