Bestselling witchcraft author Trish Sinclair has a shameful secret: she’s a lousy spellcaster, and the spells in her books belong to others. So when a dying warlock entrusts her with an ancient and powerful grimoire, she runs for her life from his murderer, psychotic witch Kate Cavanaugh. Kate pursues Trish relentlessly to obtain the grimoire, which holds spells to command the fearsome power of a magic crystal hidden in town—and Kate is determined to have that power.

When the town coven refuses to help Trish protect the grimoire, she is forced to turn to cynical warlock Aidan McCarthy, who has a secret agenda of his own, and Rain Devereaux, a novice witch whose spellcasting abilities are even worse than Trish’s. As Kate unleashes the elemental might of tornadoes and ice storms on the trio, they desperately struggle to defeat her.

But Kate is too powerful, and she manages to steal the grimoire and unearth the crystal. Trish knows Kate will use the stone’s power to exact her deadly revenge on Aidan and the town coven unless Trish can manifest her latent magical abilities to save them.
