OK, you pushed me over the edge - I'll be ordering that one soon. Books where it looks simple and you spend a month on a single page can be pretty discouraging. It's good to have one you can make steady progress through.
I already have a chord tone soloing book, well, it's actually called "Scales over Chords - foundation of melodic soloing" by Chad Johnson. I may dig into that before getting the MI book on chord tone soloing.
Ugh - just realized I own a Tom Kolb book on Music Theory. I'll have to check in on that as I go to see if it offers help.
Maybe I'll finally make use of all of these book I bought and left to collect dust.
