This is a book for older teens, rather than the all-ages Thirteen Treasures series. It's a satisfying ghost story, with a well thought out ending, sympathetic characters, and a believable (for a ghost story) plot. Elliott, aged 17, has had an accident when he briefly "died", and since then he can see ghosts. At first he is terrified - and so is the reader - but then he decides to confront his problem by actively seeking out a haunted place. He goes to work in an open-air museum, which does ghost tours, and does indeed have more scary experiences, but also falls in love with an enigmatic girl who works at the museum. Gradually he comes to believe that the ghosts want to communicate with him to ask his help, and this leads him to uncover their stories, which are fascinating and plausible. One ghost in particular, though, seems intent on taking over his body - and his girlfriend, and this leads to a nail-biting ending for this well-written book.
