This book looks very interesting. I wish Manning would publish more cohesive book series around specific topics, such as software architecture, where one book naturally builds on the previous one. Sometimes Manning books on certain subjects feel disconnected, which I think is largely because it is rare for the same authors to write multiple books on the same topic there.
I really like what O’Reilly has done with Mark Richards and Neal Ford. You can clearly see a structured learning path across their books, although I should admit I haven’t actually read any of them yet.
