Wings of Sorrow and Bone was nominated for a 2015 Nebula award. It is the second to last story in Cato's Clockwork Dagger series. This story is told from Rivka Stout, the daughter of Caskentian princess Mrs. Stout.
Rivka is a talented mechanist, but was born with a cleft palate and is generally poorly treated in Caskentia. She confronts Mr. Cody, the creator of gremlins, over his plan to construct a second large gremlin cyborg to compete in Warriors, the favorite action/strategy game in the area.
There's not a lot more to the plot, except for her complicated friendship with Tatiana Garrett, sister of Octavia Leander's paramour Alonzo Garrett from the previous books. The story is a little blocky and pat, really just kind of edges in there as an award nominee.
There's one more story in the series, but I don't feel particularly compelled to read it. I'll give this one three stars, weakly. It's OK.
That wraps up my reading of Nebula nominated novellas for 2015. I liked The New Mother, but Waters of Versailles probably comes closest to my style of story--velvet water pipes! Wild!
