Dorianna by Catherine Stine.
Evernight Teen, 2014
Barnes & Noble: Internet followers, beauty, power. It all sounded good.
Until it transformed into a terrifying reality Dorianna couldn't stop.
When her father is jailed, her mother ships Dorianna to her aunt's house. Dorianna yearns to build a new identity, but the popular Lacey bullies her-mostly for getting attention from her ex, Ander.
Ander takes Dorianna to Coney Island where Wilson, a videographer, creates a stunning compilation of her. She dreams of being an online sensation, tired of being plain and lonely, and vows she'd give anything to go viral. Wilson claims he's the Prince of Darkness and offers her the beauty and fame she's dreamed of — warning her that a pledge has its downsides. Dorianna has no idea of how dire those consequences might be.
