Just added the first one to my Libby hold list - it sounds interesting. It's only 144 pages though, that's a really short amount of time for a complete story...
They're short but they're paced extremely well. I have never noticed how short they are while actually reading because it's a full and engaging story. I am in love with Murderbot and it's only gotten better as the books go on.
Yeah, most of them are novellas, with a couple of full-length novels. They're all complete stories, though with ongoing threads carrying through, and best read in order.
