Romancing the Duke by Tessa Dare (2014)

The first in the very delightful Castles Ever After series.

Utterly charming romance novel about the daughter of a famous author who inherits a castle, which just happens to have a reclusive, scarred Duke living in it. 

 Lovely romance with great characters, humor, and very slight and sly nods to contemporary life--blink and you will miss them. So very, very romantic and a little sexy. Yay!
