What are some other books as fundamental as DDIA?

Question

There seem to be no doubts regarding the quality and importance of DDIA for backend engineers. I keep rereading particular chapters over and over again and there are new things for me every time depending on what I encountered and thought about at work.What are some really important and fundamental books especially for backend engineers that you consider to be at least close in quality to DDIA?I often suffer from analysis paralysis so I whatever you come up with here, I will read within the next few months :)
