Daywatch, Sergey Lukyanenko and Vladimir Vasilyev
Very satisfying followup to Nightwatch - supernatural battles between good and evil in and around Moscow. I eagerly await the English translations of the next two books.
Throne of Jade and Black Powder War, Naomi Novik
Whatever muse Naomi Novik tapped in to for the first Temeraire book remains in full effect. Superb page-turners. Hurry up and write some more.
Empires of the Word, Nicholas Ostler
A history of the languages of the world. Competently written, and I learned a lot, but not quite well written enough to keep it from turning into a slog by the end.
