I just followed the course on Distributed Systems by Maarten van Steen at the University of Twente. It was brilliant, and he has written a book on Distributed Systems. It is freely available via https://www.distributed-systems.net/index.php/books/ds3/

The class I took used 'Distributed Systems: Principles and Paradigms' which is an older book by the same authors and it was great.

Maarten is one of the best teachers, if not the best teacher I ever had. I was lucky enough to have him as my teacher for three major courses in my curriculum: Computer Networks, Operating Systems, and Distributed Systems.
