The book was good and when I read it, it was helpful as it came out just as I was going from manager of a team to having to split that team and take over a few more in a group. Plus Manuel, one of the authors is a really friendly guy that pushed the Lisbon tech meetup scene forward around 10 years ago when nobody was having any regular local meetups and he was traveling between Spain and Portugal on the regular to make them happen (or so I remember). I presented my first proper talk in one of his meetups and I remember that going well and giving me a lot of confidence for other things later on. Definitely read it if you need to think about groups of teams!
