The Self Sufficient Backyard by Ron & Johanna Melchiore

Hi, has anyone read this book? A few things caught my eye: (1) seems to cover lot of topics (2) emphasis on small acreage (3) gardening with a bad back (4) they live in Saskatchewan, i.e. a cold place. (5) they've done this for 40 years.

There's a fair amount of description of its contents on their website https://selfsufficient-backyard.com/my-book/. It even includes a near-passive all-year greenhouse!

The book is a little on the pricey side ($37 + S/H) so any thoughts on this or earlier work by the authors will be highly appreciated.

I am bringing this back to the top to see if anyone, by chance, has read this book and what he/she thinks of it. I am thinking of getting it for someone for their birthday, but want to be sure the price is worth it.
