And I Darken by Kiersten White
I liked White’s paranormal romance series, so I was interested to pick up this historical/fantasy series as well. This story is about a brother and sister, children of an Eastern European prince in the Middle Ages. They are sent to live in the court of the Ottoman Empire as assurance of their father’s cooperation. There they befriend the sultan’s son and take part in many intrigues and adventures, from an aborted coup to a failed siege. The story is dark and violent, with Lada, the sister, as a particularly prickly and tough warrior-princess. Her insistence on receiving military training, and on assuming command of a regiment, pushes gender boundaries. The climax is exciting, and the ending bittersweet. It’s YA, but probably on the ‘mature’ end of the genre.
The sequel, Now I Rise, comes out this year.
