Looks awesome. I just wanted to mention a couple stylistic things I noticed in the sample copy: subsubsection under Part 1 named "It;s all about communication" (the it;s), and the capitalization style for section titles is pretty inconsistent. I don't know if you'll have an editor go through everything later on, but just wanted to mention a couple of the things from the early access sample :)
