I enjoyed the concept more than the actual reading of the book. The unreliable narrator was fun, but was too much at times. The quirky style (corrections of the diary entries, the chapter quizzes at the end) didn't really work for me. And the big plot twist at the end didn't make that much sense to me. But it wasn't entirely bad. Some of the dark humor worked and I enjoyed the atmosphere of the book. But wouldn't pick up again.
