Last summer… Quinn was surprised to find herself falling in love with her best friend Dylan. Dylan had always lived next door, worked at her family’s summer camp, and been part of the family. But suddenly she saw him as something more. The only problem was: Quinn’s younger sister Fern, and older brother Bear, were both falling in love with Dylan, too. This winter… Dylan is gone. The tragic accident that took his life has driven a wedge between the three Sawyer siblings. And Quinn is convinced it was all her fault. She’s a monster like Wessie, the deep-sea creature who, local legend has it, is lurking somewhere off the coast of her Maine home. Quinn is certain that the only way to confront the monster within herself and save her family is to repair the boat from the night of the accident, and go in search of Wessie. But as she begins to fall for a new boy in town, she begins to understand the truth about her siblings, herself, and monsters—real, and imagined.
