A lot of stuff because sticking on one book is hard: A Knight of the Demon Queen and Magistrates of Hell, both by Barbara Hambly -- the first one is a Winterlands novel and the second one is an Asher/Ysidro novel. They're both rereads, though I've only read Knight of the Demon Queen once before. Also, Witch Week by Diana Wynne Jones; I'm on a Chrestomanci rereads. A couple of other things that I keep picking up and putting down, which are also rereads: Wheel of the Infinite by Martha Wells and The Walls of Air by Barbara Hambly, the second Darwath book.
What I've just finished reading
The three Haflbood Chronicles by Andre Norton and Mercedes Lackey -- The Elvenbane, Elvenborn, and Elvenblood. The first Chrestomanci book, Charmed Life (also my least favorite Chrestomanci book -- Cat sort of irritates me, and I like Christopher better, so I'm looking forward to hitting The Lives of Christopher Chant in this reread). Also, rereads of Barbara Hambly's Blood Maidens and Scott Lynch's The Lies of Locke Lamora. And various short stories by various authors.
What I'm reading next
I've got Star Wars: Catalyst and Rogue One out from the library, so I want to read those -- I'm hesitating over buying the novelization, because I'm notoriously wary of novelizations, but this one got highly recced. (Of course, Stover's RotS novelization is highly recced too and I HATE IT, so like. I'm extremely dubious of recs.) And then more Chrestomanci and undoubtedly more Hambly.
