I'm not just starting in medias res with the series. I've watched the show, I've read the first couple books, and I also have my copy of Osiris Reborn pre-ordered. I've done some expansive homework on this topic. Okay, that's the only dad joke I'll put in here, I promise. Abaddon's Gate is a continuation of the science fiction story that the duo known as James S.A. Corey have laid out in the first two books. The protomolecule has already had a lasting impact on the solar system and life as we know it. Nevertheless, Protogen is shut down and Mao is in the slammer, Holden and his crew have been running missions for the OPA for months, Avasarala is doing what she does best behind the scenes, and Bobbie Draper... well, I guess we have to watch the show to find her ...
