As a child, Jacob formed a very special bond with his grandfather over his bizarre tales and photos of levitating girls and invisible boys. When Jacob turns 16, he is traumatized at his grandfather’s death. Then, Jacob receives a mysterious letter that propels him on a journey to the remote welsh island where his grandfather grew up. There, he finds the children from the photographs alive, despite the fact that they were seemingly killed decades ago. This novel is filled with mystery and suspense. I would definitely recommend this for all teens who like mysteries.
