Raven’s Rise. Swordcross Knights, #3

Claim your heart's desire.Lady Angelet has spent her whole life as a pawn, acquiescing to the wishes of others. She's been a good daughter, a good wife, a good mother, and a good widow. The reward for her obedience is nothing more than a one-way journey to a nunnery. Outmaneuvered by her shrewd father-in-law, Angelet is forced to accept her fate. The knight who is hired to escort her has other plans.
Now known as the undefeated Knight of the Raven, the low-born but charming Sir Rafe has had to fight for everything he's ever had. When he sees Angelet, he's more than willing to fight for her too. Rafe makes the soon-to-be cloistered lady a salacious offer: for the duration of the journey, she can spend every night with him, and she doesn't have to be good at all.  When a deadly pursuer threatens them, Rafe defends Angelet's life even though it means revealing his dark side.
But Rafe isn't the only one with a secret, and now that she's sampled the life she's dreamed of, Angelet is done being a pawn. The third book in the Swordcross Knights: A series of full-length historical romance novels set in the vivid and beguiling world of medieval Britannia.
