Six Wakes by Mur Lafferty. Awesome tale of 6 travelers on a space ship, trying to figure out who among them is trying to kill all of them. Agatha Christie in space!
The Wrong Stars by Tim Pratt. Space opera — pirates, aliens, wormholes, etc. Fun but not that memorable.
Beneath a Scarlet Sky by Mark Sullivan. World War II escapades of a young Italian spy. Based on a true story, very engaging.
The Wolves of Winter by Tyrell Johnson. Post-apocalyptic tale of survivors in the Yukon. Ok but pretty well-trod ground.
