On a night of relentless rain, twelve-year-old Clara Vale sees a white horse emerge from the forest.
Its rider is losing pieces of his skin to the storm-until only his clothes remain, wrapped around an invisible body. Before disappearing, he leaves Clara with something impossible: a fragment of skin bearing her name and tomorrow's date.
The mysterious rider is Jonah, the brother Clara never knew she had. Dead for twelve years, he is trapped between worlds, hunted by the Keeper and slowly vanishing. As Clara follows his trail through Coldwater Hollow, she uncovers a buried family secret, the truth about her frightening gift, and the white horse Angie's connection to the night that changed everything.
Then the graves begin to open.
Julio rises from the earth covered in blood and worms, consumed by a hunger for the living. As endless rain floods the town and terrified survivors seek refuge inside City Hall, Clara and her companions must find a way to destroy him before Coldwater Hollow becomes part of something ancient-and alive.
Some doors should remain closed. Some dead should never return. And sometimes salvation comes from the one creature everyone underestimated.
