For the most part, I enjoyed this book. The writing was decent and the characters were well developed. The main issue for me was the plot. I just didn't buy it. 
 Three adults (counselors/psychologists) and eight troubled teens spend four days on what is essentially a camp for delinquents located on a deserted island. The only way to get there is by boat. Each teen is sent to the island for various reasons like excessive drinking, theft, drug use, etc. The book is told from the perspective of Alice, who is there for excessive drinking and Caleb, who while trying to protect his mother, assaulted his abusive step-father enough to put him in the hospital. As much as I absolutely think what Caleb did was necessary and I applaud him, the courts still see it as a teenager putting an adult in the hospital. Whether deserved or not, they see him as a danger to society. Sending him to what basically amounted to deserted island camp just seemed like a weird thing to do. It seemed strange to put kids that were convicted of drug abuse, breaking and entering, theft, alcohol abuse, and assault, together on an island with only three adults, all of which quickly proved to be completely inept. Granted if ten adults were present, there wouldn't have much of a plot, but still. There was literally one radio on the island. The entire thing seemed ridiculous to me. 
 Things become interesting when one of the teens disappears and one of the adults dies (not a spoiler, it's in the synopsis). An interesting dynamic develops between the characters. Each person has to decide who to trust and work together to figure out what exactly they are up against. Suicide? Murder? 
 I enjoyed the mystery. I found myself yelling aloud, "AHA! I knew it!" as the clues came together. No one suffered from TSTL syndrome and the characters and their responses to their situation were realistic. It always bothers me a little when the villain is finally unveiled and they give the obligatory three-page mustache twisting spiel on motives and means. I know the purpose it serves, but it just seems a little lazy to me. 
 Overall it's a fun read if you can suspend belief a little.
