Books
Red City, by Marie Lu. Billed as "The Godfather meets the Magicians" and that's probably a decent shorthand. The magic system is fantastic and I'm going to steal bits and pieces of it for games I'm in. The story and characters and twisty plot full of people with questionable morals was also very good. I'm in for the next one, though I can't tell if this is two or three for the series.
The Conductors, by Nicole Glover. First in a series of post-Civil War (US) fantasy mysteries featuring a married couple who were conductors on the Underground Railroad. She has the magic (and it's an intriguing system) and he's got brawn. They both have brains. The mystery is good and by the end of the book they're nicely set up for more stories. I'll read the next one.
The Last Note of Warning, by Katharine Schellman. Third and next-to-last, apparently, in this queer Harlem nightclub mystery series. Our protagonist runs into another murder that's connected to the lady boss she's into and puts her in need of help from the Commissioner's nephew, the other side of the romantic triangle. I think the romantic arc is coming to a climax so the next one may be a good endpoint, but I'm there for the rest of the ride.
Viviana Valentine Gets Her Man, by Emily J. Edwards. First in a series about a NY private investigator's Girl Friday in the 50s. This time she's solving the mystery of an heiress who apparently has a secret boyfriend. These came with the recommendation of a friend and they're fluffy and cute and I quite enjoyed the first, so I'm in for more.
Unabridged: The Thrill of and Threat to the Modern Dictionary, by Stefan Fatsis. I've had the Kory Stamper book in my to-read for a while so this one was a natural. I quite enjoyed the history and was depressed by the modern prospects for the dictionary. Fatsis did a great job of showing what dictionary work has been like over the decades and how it could improve. It's still going to require money to do it, though, as is the problem with every kind of pure knowledge acquisition.
These Summer Storms, by Sarah MacLean. Halfway between a romance and a family saga, this is the story of the four kids and widow of a billionaire tech overlord who can't stop fucking with people even after he's dead. The main POV character is the daughter who walked away for reasons you find out during the book but other characters get their chance too. The just too good to be true romantic foil is the one whose interior I really wanted to see and didn't The final twist is perfect, though.

Short Stories
The Final Voyage of the Ouranos, by Marie Brennan. I always enjoy Brennan's work (except for her Victorian pastiche, which lost me) and this is no exception. Super creepy raypunk-esque history of a lost/destroyed aether-ship.
Bots All the Way Down, by Effie Seiberg. A perfect little bot bedtime story, with a lovely ending twist.
Slake, by Victor Manibo. A horror story about a high rise and a hurricane which was kind of freaking me out (I grew up in hurricane country and have been flooded in).
