She's the ultimate weapon in fighting Destiny.

New York Times and USA Today bestselling author Suzanne Brockmann and her daughter Melanie have written a pulse-pounding novel of paranormal suspense set in a near future both fantastic and frightening.

Skylar Reid is shaken when Sasha, the little girl she babysits, is kidnapped. She's scared that the weird dreams she's been having about Sasha are real—and even more afraid that Sasha is already dead. When a mysterious girl with extreme butt-kicking abilities roars into town on a motorcycle and starts stalking Skylar, things get even weirder. Supergirl Dana tells Sky that she also has abilities, that a hormone in their blood makes them stronger, faster, smarter—a hormone that the makers of a new drug called Destiny will murder to get their hands on.

Dana and Milo, her dangerously hot yet oh-so-forbidden partner in crime, want Sky to join them in their mission—and to mold Sky into the ultimate weapon. She can sense there's something about her abilities they're not telling her, but the only way to save Sasha and stop other girls from being taken is to embrace the weird ... and fight Destiny.
