When the creatures in her dark drawings come to life, Chelsea finds that the mysterious Geoff is the only person she can confide in. But she can't help wondering who she's kissing: her tender confidant or the dangerous Byronic rebel bent on shocking his detached father. Starting over in the South Carolina Lowcountry is just what sixteen-year-old Chelsea needs. Unfortunately, moving also means living with her mom's snobbish British novelist employer and his moody son Geoffrey. Knowing that her new home likely used to be a slave holding plantation doesn't make her feel any more at home. Troubled and reckless after his brother's mysterious death, Geoff often mimics his father's literary favorite, Lord Byron, acting "mad, bad, and dangerous to know." She's determined to keep her distance and buries herself in her art, though the darkness of her drawings troubles her and others who see them. When people in the Gullah and Geechee community point out that she has been drawing Boo Hags and haints -powerful and terrifying creatures of local legend and superstition- she starts to wonder about her own heritage and her connection to the Sea Islands. She begins to question her own grasp on reality when it seems those creatures start making their way out of her drawings and into real life. It's clear that Geoff has some secrets of his own, but he might be the only person she can confide in. Chelsea must decide who she can trust, when nothing in the Lowcountry is what it seems.
