For me, best of 2023 was Red Team Blues by Cory Doctorow. A retirement-age forensic accountant traveling around in an ex-rock star bus from Walmart parking lot to next gourmet dining location does a job for a billionaire and suddenly ends up in a surprising amount of hot water over it. Hijinks ensue.
Runner-up goes to Venomous Lumpsucker by Ned Beauman. This is some bleak, bleak humor. Instead of carbon credits, Beauman posits extinction credits. Got a big strip mining operation coming up that will kill off a couple species? Better buy some extinction credits to cover their death! (And remember, it takes more credits to cover for a dead intelligent species, so factor that in!) Next extinction candidate: the Venomous Lumpsucker, but don’t make it extinct until you’ve got all your paperwork done. Researcher and extinction credit manager for a mining company end up in a desperate chase around the planet trying to ascertain if the last of the Lumpsuckers are truly gone or not, and we go along for the ride.
Yeah, finding the new stuff by authors you like can be tricky sometimes. I basically use this list to help me track new releases. It’s doesn’t cover 100% of new releases but it does get quite a few. Plus, my library lets me request/place holds on books 2 months before they release so usually I can be one of the top 3 in line for pretty much anything new (although it can take them a couple weeks to a month to actually get the book).
