I wonder what kind of people would read an epub in a terminal.

I notice that many of the tools (at least in the repos linked) seem to have stopped development since a couple of years.

As some of these are wrappers for tools or use APIs that could mean that they do not work any more, or without special configuration. Or that things are stable, and the tools are "done".

Just got a quick look, and found a gem: https://github.com/maaslalani/slides

Easy to use, neat and powerful!
