The information contained in this book is enlightening.
It certainly opens up another resource for APs.
I particularly enjoyed the meat contained in chapters 6 & 7.

As a newbie to AP blackjack, it's tempting to change
direction and learn advantage Sp21, but that can wait
for the future. Hope this decision isn't a mistake!

I can truly recommend Mrs. Walker's Sp21 book as a
positive EV purchase.
