I think Lost has burned me so deeply that any mystery that I start just makes me instinctively think "is this another Lost?". When I started this book that's the first gut feeling I got. All the characters, with names and codenames, also made it hard to follow. But as I kept reading, and reached this middle point, I can say I am hooked. The characters are interesting, and I think I can sort of follow who is who (this is something that happens more to me in written mediums instead of TV/film). The mystery is there, but I think what really hooks me is the characters and their relationships to Walter. At this point, I just want to know more about Walter. Not what he is, but who he is.
