1) James S. A. Corey: Leviathan Wakes (audio, finished 01-17) The first book of the Expanse series, I started the audio version pretty immediately after finishing the first season of the Syfy TV adaptation. The series has been described as "Game of Thrones in space", which isn't too far off, but the book has a much narrower perspective as it only follows two people's points of view for all but the prologue and epilogue. Both are excellent, however, and now I need to decide whether to continue with the books right now or wait for the second season of the series to air.
2) James S. A. Corey: Caliban's War (audio, finished 01-22) So obviously I just went ahead and continued listening to them. The second had a bit more of the politics that characterized the first TV season.
3) James S. A. Corey: Abaddon's Gate (audio, finished 01-28)
4) James S. A. Corey: Cibola Burn (audio, finished 02-06)
5) James S. A. Corey: Nemesis Games (audio, finished 02-10) [finished the novella The Vital Abyss the same day]
