After fleeing family tragedy to his grandmother's home in the small town of Raven Hollow, free-spirited photographer Caleb Reed stumbles upon a legend made real: Willow Thorne, a nine-meter-tall witch cursed by a lover's betrayal centuries ago, feared by the townsfolk as a monster that devours hearts. Instead of running, Caleb leaves her sandwiches, an old scarf, and his clumsy sincerity—slowly thawing three hundred years of lonely isolation. But the Ashen Order's witch-hunters close in, his jealous childhood friend turns informant, and the only way to break the curse is a kiss of true love from a destined soul. As the curse is bound to Willow's very life, and the whole town raises its torches, Caleb must decide whether one kiss is enough to give her back the human world she has waited centuries to see.
