Sometimes in a novel when you go down the well you have to put the lotion on your skin, other times you're travelling back to Earth. The latter, this one is the latter.
James Holden and his crew of the Rocinante are back again serving as an ad hoc belter law enforcement when they are sent to investigate an incident on Ganymede. Things quickly circle the drain from there as the war between Earth, Mars, and The Belt threatens to start again at any moment. Oh, and Venus is now under alien control. Fun times.
This is the second novel in The Expanse series by James SA Corey (aka Daniel Abraham and Ty Franck) and as a sequel to Leviathan Wakes it delivers. I thoroughly enjoyed the further adventures of the Rocinante crew, but the new characters of Bobbie, Prax and Avasarala only added to fuel to the fire. Avasarala in particular is a great character to follow, making the political side to the story palatable (Avasarala is portrayed by Shohreh Aghdashloo in the TV series, and I'm sure the writers had her in mind when the character was created).
I guess that means it is time to start reading the third novel in this series. Tough job but someone has to do it.
