I read cozy and historical mysteries, a bit of Paranormal/UF, and to mix it up, I read science and gardening books on occasion.
A very comprehensive (very) overview of creating a sustainable, edible garden that strives to be carbon and water usage neutral. Lots of great information here that would apply to any gardener anywhere (finally, I found easy-to-understand pruning information) although the charts for growing times and harvest times would be useless to anyone not living in the Southern Hemisphere.
My only complaint is that while the book had lots of great full-colour photographs, it didn't have any of the completed project as a whole. I really wanted to see the big picture - including the outdoor bathroom!
Will be handy reference as I continue to experiment.
