This book was weird...I love weird. The information was presented in various ways including video recordings, handheld camera shots, and notes passed between Niamh who is mute and A. And it wasn't too weird that I was unable to follow the plot of the story. I liked how it was part ghost story part sleuth mystery...it definitely kept me on my toes and I had no idea how it was going to end. I didn't mind how it ended except for one detail, but it was bound to happen. This is the kind of book that one has to read a section at a time. The book is broken up into three parts and an epilogue, and I noticed that I would kind of forget what I had read if I stopped in the middle of a part because so much is constantly going on throughout the book. But this book is excellent. It is fast-paced and keeps the reader guessing up to the very last page.
