The plot in the beginning is a little slow which lulls the reader into a sense of security. It starts to look like this is going to be just another run of the mill mystery with an easily guessed outcome. But once the first big twist is revealed everything changes. The plot becomes intriguing and exciting as we try to figure out exactly what is happening. The writing flashes back and forth in time as we discover what led up not only to the "break up" between June and Delia but also to her suicide. The side characters come off a little bland and could use some development but June and Delia are fantastic. Everywhere that June is careful and thoughtful, Delia is wild and erratic. It is really her character that is the standout. Much of the novel concentrates on discovering just what motivates Delia's actions and examining the odd relationship between her and June.
There are some issues within this novel that would stop me from recommending it for younger teens. There is a great deal of underage drinking and drug use as well as crude sexual remarks and attempted rape. Some of this is pivotal to the plot, but I'm not sure all of it was strictly necessary.
Bottom Line: If you think this book is just an average, run of the mill mystery, stick it out. It will surprise you in the most incredible ways.
