Chilling and mesmerizing

Wow. Once I started reading Unwind by Neal Shusterman, I could hardly put it down. The main idea is creepy, the pace is almost non-stop, and the way some of the characters changed (some for the better, some for the worse) was both believable and fascinating. The time is in the future; parents can choose to have their children ages 13 to 18 unwound - although "technically" they're alive, all of their body parts are harvested and given to others. This story follows Connor and Risa, as they desparately try to avoid the harvest camp, and Lev, the 10th child born to a family whose religion considers him to be a tithe - being unwound is his sacred duty. The action starts immediately, and the twists and turns made me feel like I was on a roller coaster. Some of the ideas might be a little too intense for younger readers, but this would be amazing for older students to read and discuss - so many questions come up! When does life begin? When does it end? I was thinking of this book long after I finished it.
