Flame in the Mist by Renee Ahdieh

I absolutely loved The Wrath and the Dawn, so when I heard that Renee Ahdieh was writing a retelling loosely based on Mulan I was very excited. And I was not disappointed. I think it was Roshani Chokshi who described Renee Ahdieh's writing as "butter", and I cannot think of a more accurate description. It is rich, and smooth, and velvety, and makes you wonder how you managed without it before.
