I'd recommend this to beginner piano and guitar students (Ross Trottier is a guitarist himself).

It started off well, but I soon got lost. With a lot of effort sometimes I could make sense of something by re-reading it over and over, but eventually I just gave up. Although given how many good reviews this book has, perhaps I'm just a lost cause for music theory.

I found the book a good way to go deeper but I started with you tube videos from the same source. The purchase of the book was more to support the creator.

I learned a lot

And one of the things I learned is that I still have a lot to learn! Somewhere in the midst of chord inversions I got a bit confused, but I recovered in the circle of fifths and key signatures. Practice is definitely necessary in order to fully absorb this material but I feel the book was written well and provided a solid base for my curious mind!

Excellent, short lesson. Starts from scratch. Builds methodically. Great use of visuals/charts/grids to show how it all relates.
