Eila Walker knows luck is not a friend, so she's downright shocked to inherit a million-dollar Cape Cod home. And yeah, her new town isn't perfect: the cheerleaders are heinous clones, the local rip current can kill you, and apparently her Great Grams was fried by lightning in the harbor square. Still, Eila is hopeful her luckless days are in the past. When Raef O'Reilly becomes her friendly shadow, Eila thinks life is pretty darn perfect. But just as her new hometown starts to feel normal, a beach bonfire party turns into a nightmare when she's hauled beneath the waves by an undertow WITH ARMS. Raef, no longer able to hide the truth from Eila, must come clean: she's possibly the last of her kind, a supernatural assassin who should be able to wield the power of human souls as a weapon, just like her murdered Great Grams. Soon Eila finds herself under the protection of Raef and an outrageous crew of allies. Unfortunately, she's now the hottest Must Have on the supernatural black market, and the teenage gang that is trying to guard her is woefully lacking . . .
