I loved the whole getting the band back together vibe. Perfect blend of humour and fantasy elements . <Proper review TBD>

Dull. Really dull. 
Plenty of opportunity for character growth but they are all so flat. The main character does nothing but pine for another character. I feel like I know nothing else about her. 
The entire premise of the story is entirely predictable after the first quarter or so too. I finished it for completion rather than any need to find out how it ended. 
Overall - dull.

No better book on the nitty gritty of calisthenics. 

There isn't really anything else to say about this book. It's the definitive (and weighty) tombe on calisthenics and bodyweight programming. If you have started something like the Reddit /r/bodyweightfitness recommended routine and are wondering why things are programmed the way they are, then this book is a great explanation of everything.
