When Erika wakes up after a horrific car crash, she finds herself somewhere between earth and heaven, between life and death. She doesn't want to accept help from Jeremiah, who she's not sure she can trust, even as she finds herself drawn to him, following him into a grim city of souls. She's not sure who wants to help her and who wants to hurt her. And she's desperate to get back to her children. Shawn has never thought about having to shoulder the responsibility of caring for his young sister Megan and his reckless older sister. And he never imagined that the three of them would find themselves in a haunted wood-sometimes chased, sometimes assisted, never sure where they're headed. With Grim, the terrifically talented Anna Waggener delves into the place where myth becomes reality, where family can distort you as easily as it cares for you, where death and eternity meet.
