A darkly quirky, Tim Burton-esque story about a guy who discovers that all his grandfather's fantastical stories were true, and he travels to a tiny British isle to discover the truth about the "peculiar children" and the monster only he can see. I enjoyed the bizarre atmosphere supplied by the old found photographs the author intersperses throughout, although sometimes the photos felt a little shoe-horned into the narrative, like he was completing a writing exercise: "tell a story that explains these 16 photographs."
I also enjoyed the narrator's voice. I may have been enjoying it as an adult, though, so I look forward to hearing feedback from my teen readers. It strikes me as a book written for adults, but the teen character and the strong market for all things teen and supernatural meant it was released as a teen novel.
The story lost a little steam near the end for me, but that's nitpicking. Still an enjoyable and memorable read. The blatant cliffhanger points to sequel.
