Locus Amoenus: All By My Shelf

One thing I have to say about this series is that, although the page counts seem daunting (500+ per book), they really fly by.

Another aspect I love is how well you get to know all the new characters that keep popping up. Aside from Jim Holden and his crew, every book so far has had a different supporting cast of characters. Every chapter is told from a different perspective, though, so by the end of the novels you understand what makes everyone tick. I only wish some previous characters came back (a couple do in this one): I miss the foul-mouthed elder stateswoman Avasarala, and her sidekick Bobbie the Martian marine!

Also, the main series story line, following the development of an alien protomolecule, just gets creepier by the book, and I'm loving that as well.
