A slow year for me, 2018. Hope to do better in 2019. I'm calling 2018 "
The Year of the Romp." Because that's what my two favorites this year were.
Daryl Gegory's
Spoonbenders (what I've described as
Arrested Development's Bluth family meets
The Men Who Stare at Goats) and
Sea of Rust by C. Robert Cargill (a robot western) were this year's standouts for me (both published in 2017).
I also really enjoyed discovering Emma Newman's writing this year. The three books (so far) in her Planetfall series were quite good (though not at all what I'd call "romps"

).
