Mimi's never been afraid of ghosts. It's humans that freak her out.

Etherall Valley Academy. It's an elite school for students facing "unique challenges" ? so there's going to be drama.

Mimi's unique challenge is her trio of invisible companions, but nobody can know about that. Her plan is to blend in, keep her head down, and simply survive her final year at this new high school.

That's until she's selected for the school's gifted program. It's a class like no other: seven very different teens with talents Mimi never suspected. Among them is bookish Drew, dark and solitary behind his facade of spikes, piercings and dramatic makeup. He barely looks at Mimi, and yet she always has a sense he's watching her.

Their mentor says their gathering is a convergence of their powers ? that they must learn to use their gifts in balance and connection ? but that's not easy when secrets, rivalries and desires are in play.

Mimi just needs to survive her final year of high school. Literally.
