Are you looking for books that have a certain theme / subject that fit the music of MaSu? If so, I can't really help you.
If you know Dutch, you should 1000% make sure you read 'De Engelenmaker' by Stefan Brijs. If you don't mind reading translated novels, you should read 'The Angel Maker' by Stefan Brijs.

It's one of the best books I have ever read. It's about a doctor who has 3 identical sons and named them after the archangels. The children never come outside and the townspeople suspect the father from testing upon them. Insane book!
For English literature... if you're into fantasy and haven't caught up with Game of Thrones yet. Uh, do so!
For other English literature, you should really check out Alice in Wonderland / Through the Looking Glass. Moby Dick is awesome as well.
