One of 
my favourite reads last year was J. S. Dewes The Divide trilogy. When I learned that she’d also written a standalone novel, Rubicon, I had to pick it up.
It is set in a world where humanity lives on two planets orbiting a dying sun (just how imminent the death approaches is a topic somewhat up for debate) and is at war with a race of sentient robots, known as Mechs. Adriene Valero is a “pathfinder” in a military unit (sort of a mixture between a recon specialist and a land surveyor), who, at the beginning of the book, dies for the ninety-sixth time. After her resurrection (this is a world where technology has somewhat-recently made this possible, and is standard for military personnel), she is reassigned to a secretive, high-tech unit and becomes involved in an effort to end the war with the Mechs once and for all.
I didn’t like this quite as much as the author’s previous novels, but it was still a really good read. Something about her writing style really works — it isn’t funny, per se, but it’s got sort of a dry cynical wit that makes it very readable to me. Also a highlight is the character work — the setting is very high-science-fiction, but the heart of the novel and it’s driving force is Adrienne dealing with the trauma from her past experiences, and establishing connections with others.
Overall, this was great! Would recommend it to anyone that likes well-written character-driven works (even if they may not be really a fan of science fiction).
