Summary: Girls Blue describes the summer of Riho and her friends. They don't know what the future will bring and they also don't have big plans or goals. Riho just got dumped by her boyfriend and her friend Misaki doesn't have a very good health so she ends up in the hospital quite often. Then there is a someone who has been poisoning the cats in their area?
Opinion: I really liked this book, despite few big and/or exciting happening in it. Just when you think the story will take a turn in a certain direction, it doesn't happen. The end of the book didn't really feel like the end. I felt like the story could go on and on.
