Told in alternating voices, years after it began, seventeen-year-old Ivy and her mom Dana's shared story comes down to a reckoning among a daughter, a mother, and the dark forces they never should have messed with. Ivy's summer break kicks off with an accident, a punishment, and a mystery: a stranger whose appearance in the middle of the road, in the middle of the night, heralds a string of increasingly unsettling events. As the days pass, Ivy grapples with eerie offerings, corroded memories, and a secret she's always known: that there's more to her mother than meets the eye. Back then, the summer Dana turned sixteen, her gifts bloomed into a heady fling with the supernatural, set in a city of magical possibilities and secret mystics. With her best friend and an ambitious older girl, Dana was speeding toward a violent breaking point. Now Ivy and Dana's shared story will come down to a reckoning among a daughter, a mother, and the dark forces they never should have messed with.
