This was an enjoyable little book. It moved along at a nice, streamlined clip and all the characters were likable and fleshed out gradually which can be a tricky thing to do. Maybe one or two scenes could have been added for better effect, for example: I would have liked to see Peter convince his friend to do something kind of weird on his behalf, I wanted to see how he managed to manipulate said friend.The solutions to problems weren't clean-cut and were often multiple choice, which I liked. There were some unexpected twists and nice dark humour, which I love. All in all, I'd read another book with these characters.
