I liked reading the true relationship between two troubled teens. There could have been more details given on each situation. The book was somewhat sad throughout as well.

My wife bought this at Walmart. The bag had very cheap construction, and she only used it, about 5 times, before we were informed that stitching on other parts of the bag's seams ripped.

Bad review
