Very engaging, once you start reading, you won't be able to stop. My 17 and 14 year old daughters read this, and with the exception of The Twilight series and the Harry Potter series, they NEVER read the same books. As a matter of fact, I couldn't read this until they both were finished with it. I asked them what they thought about it, and how many stars they would give it if they were to review it. "Excellent and 5 stars" from one, and "really, REALLY, I mean REALLLLY good with 5+ stars", from the youngest ( I did tell her that the limit was 5 stars ;), hence the '+'!) I've been asked to try and find some of your other books that are for YA / Teens.
