This was fast-paced and gripping, but also very tense and at times creepy. From the cover I would have expected something a bit more upbeat but it's very definitely a thriller. 

It's generally well written, although there are plot elements that don't really quite make sense. I do like the writing style, which is in the first person.

Overall I'm not sure I could really say I enjoyed the book, but I would recommend it to readers who like thrillers more than I do.
