Thanks, Chris, it's great to see the announcement! I think we've been discussing this for nearly two years of outlines at our local coffee shop.
Grumpus did all the hard work-- I only wrote the foreword, and I didn't even have to edit it.
And yes, it's a very good book. Better yet, it's a fast and compelling read. You already know that I'm not a "gut it out to 20" guy from the Command Retention Team. Grumpus will give you all the info (both financial and lifestyle) to make the decisions which are best for you.
[Best of all, and I mean this in a "mutual success" sort of way, having Grumpus' book on pre-order means that the ChooseFI publishing pipeline is clear to proceed with their next release: the money-savvy family book that my daughter co-wrote with me. We've just finished reviewing the internal layout and we should have draft cover designs on social media within the next few weeks.]
