I haven’t read any of these books, but the concept at least seems interesting. This seems to be the first attempt to write Star Wars stories that don’t either (1) rely on known characters from the mainline movies or (2) center around the eternal Jedi/Sith struggle in some way.

But I don’t quite know what to make of the High Republic yet, based off the descriptions/summaries I’ve read. The setting and backstory sounds vaguely “Star Trek” inspired, e.g. focusing more on exploration, space travel being more difficult and slow, weird sentient plant beings (I think?) as villains, etc. And of course, a sentient rock is the most Star Trek thing ever. The descriptions I’ve read and some of the imagery I’ve seen reminded me a bit of the original Star Trek movies (Star Trek: The Motion Picture, Star Trek II, III, etc.) with the Jedi instead of Starfleet. But that was just my impression - I haven’t actually read any of these books yet, so I am probably way off. Regardless, it sounds very interesting.
