Tongues of Serpents by Naomi Novik, the new Temeraire novel.
Magic Below Stairs by Caroline Stevermer. YA, set in the Sorcery and Cecilia world.
A Spider on the Stairs by Cassandra Chan. Part of a mystery series, set in modern day but with a very Dorothy Sayers feel to it.
Shades of Milk and Honey by Mary Robinette Kowal. This has been described as like Jane Austen with magic.
Who Fears Death by Nnedi Okorafor. Set in a far future, post-nuclear-holocaust Africa.
Book I'm about to start reading:
A Star Shall Fall by Marie Brennan. Fae in 1759 London.
Books I finished recently that I really enjoyed:
Boneshaker by Cherie Priest. Excellent steampunk adventure.
