Davide Nastasio from Chessnewsandviews.com has written an in-depth of this new book by Neil McDonald. The full review can be found here: Chessnewsandviews but to summarise...
"The strength of this book is the hundreds of questions posed by GM McDonald, definitely important if one is serious in improving one’s own chess.
Final thoughts: I’m happy with this book, I think I’m getting the training I paid for, and I look forward to more chess books to enrich me and teach me as chess player."
