Charisma;

A heartracing thriller from the New York Times bestselling author of NERVE, the book that launched the major motion picture!

Aislyn suffers from crippling shyness—that is, until she’s offered a dose of Charisma, an underground gene therapy drug guaranteed to make her shine.  The effects are instant.  She’s charming, vivacious, and popular.  But strangely, so are some other kids she knows.  The media goes into a frenzy when the disease turns contagious, and then deadly, and the doctor who gave it to them disappears. Aislyn must find a way to stop it, before it's too late.
 
Part medical thriller, part social justice commentary, Charisma will have readers on the edge of their seats.
