In terms of well-written fun I would rank "Murderbot Diaries" very highly, alongside any of the John Scalzi books I've read. For similar levels of ridiculous (and trying-not-to-be-but-kinda-still sexist) look no further than "Off to Be the Wizard". That one is best if you recruit a few programmer buddies to also read it, so you can all compare each other's resulting self-insert fan fiction. I'll also occasionally reread the "Synchronicity Wars" series if I'm feeling ill and want something sorta kooky.
