The ending of this book is downright creepy. I'm still not sure whether I liked the way it ended (because I thought it was unpredictable, but kind of dumb at the same time in terms of ENDING a tale like this). I wonder if there will be more books written to turn this into a series or not, but it was definitely enjoyable. I can't reveal what made the last 100 pages so horrifying, but it definitely can give you the creeps. I would recommend this to anyone who enjoys Teen fiction, Space, Sci-Fi, etc. I could also see a poorly made PG-13 film of this being made, but oh well who cares, that's why we read the books right?
