A clock is counting down, but Waverly Windswept doesn’t know it…yet. She’s too busy coping with a breakup, figuring out her life, keeping a side eye on her hopefully redeemed sister, and collecting the clues to find a buried fortune that could make a snarky-witch rich. But then, a corpse washes up on the Isle of Mer, the body of a VIP to the island’s survival, and Waverly is swept up in a tsunami of sinister con-games, obsessed cult followers, and snooty, scheming suspects happy to commit murder to make their deepest desires come true. There’s a bigger game with mortal consequences happening, and to win it, Waverly must become the witch she’s meant to be—or die trying.
