I have read 1-8 of this series. I am 15, but I don't think the series is too young for me at all. It is very suspenseful, and really hard to put down. My brother and I got the fifth one first and after reading that decided we had to read the rest of the series. Now we have 1-9 and so far I think this was the best one, but they are all very good.
This book leaves you hanging. When you read this one, you have to finish the whole series. And believe me, you'll want to! I'm not a fan of mysteries, so I like this series because it has action and suspense as well. It's a really great book.
This book was great! I usually don't like mysteries but this was real cool. It's not scary or anything. And it's not all mystery, mystery, mystery. It has touching bits too. I love Bryce and Ashley! You can't just read one book though-you have to read them all because they continue on from each other. Cool book!
