This collection follows Ashley Mizuki Robins across two mysteries. In the first, a thirteen-year-old Ashley travels to the remote Blood Edward Island after receiving a letter from her father, long believed dead, only to find him missing; while searching the island's eerie mansion she befriends an amnesiac young ghost named D and begins to uncover the truth about her mother's death. Two years later, a sixteen-year-old Ashley visits Lake Juliet at her father's invitation, where flashes of her late mother's memory draw her into a new puzzle surrounding a mysterious research device and the secrets buried around the lake. Guided by a handheld gadget and the clues she gathers, Ashley pieces together long-hidden family truths in both haunting tales.
