A worthy, though somewhat wordy, read on the nuts and bolts of managing documentation projects and people. It provided a solid foundation of theory paired with practical tips, and as an experienced docs project manager, I was able to get some new ideas out of it as well. I would highly recommended for newer and experienced managers alike.
My only criticism is that the book has some outdated references (such as to websites that are now 404s and technologies that are out of date), though they're easy to skim over to get back into the good stuff. It could stand for a new edition. I'd also like to see the many "he or she"s updated to "their" in keeping with inclusive language. Nonbinary docs managers exist, you know, I'm one of them!
