If you love tea, this is definitely a must-read. Aaron (Wu De) does an incredible job bringing together all the themes that underline his tea Tradition.
I've been part of Global Tea Hut for a while now, so for me, many of these topics aren't new, however, it's always good to read them over again.
If anything, it felt a little redundant at times, as well as a little forceful. If you don't like proselytism definitely skip this book. I don't mind it, as Wu De isn't forcing anyone to read the book. Nonetheless, it's interesting because other writings at Global Tea Hut don't feel so forceful. I'm guessing that Wu De came a long way since he published this book in 2014, and the message feels more rounded and smooth now than it did back then.
All this said (which is more of a personal thing and nothing about the book per se), if you like tea, Zen, nature, and spirituality, this is a book that will resonate powerfully.
