I had a quick look (the book can be borrowed on archive.org) and I'm not very enthusiastic about this book. It might serve as a first introduction to the topic, though IMHO it tries to cover a too broad range of topics including typical distributed systems stuff (e.g. the Byzantine generals problem). Almost $100 seems to be quite expensive for that book, though I know of the horrible inflation of textbook prices in the US. My usual recommendation for students and practitioners interested in OS theory and internals with a solid practical connection is Remzi H. Arpaci-Dusseau and Andrea C. Arpaci-Dusseau's (University of Wisconsin-Madison) "Operating Systems: Three Easy Pieces". The book is available for free as PDF from https://pages.cs.wisc.edu/~remzi/OSTEP/ https://pages.cs.wisc.edu/~remzi/OSTEP/
