This was all around fun. Actual mystery which was--for the most part--solved, and peacefully too. There was some fear induced grimacing at the end, but no actual knife-at-the-throat threatening. Clever, more than just a little, I had to scratch my head. I did not get those Pentominoes right away. The characters are very likeable and real. This is what Young Adult is. Interesting and not too bogged down with 'messages'. Yeesh.

You go, Blue!
