The Undercover Duke by Jess Michaels

Lucas Vincent may be the Duke of Willowby but he’s never acted as such. He’s been too busy working for the War Department as a spy. But years of dangerous work has finally caught up to him and he was involved in a violent attack that nearly killed him. Forced home, his angry, aggressive desire to get back in the field and find out to who betrayed him is keeping him from healing.

Diana Oakford was raised by a physician who served the King’s War Department and she knows better than most the dangers that job entails. She was also trained in healing, so when she’s asked to come and assist with Lucas’s recovery she has a hard time refusing.

Once they’re alone together an unexpected connection begins to grow between these two people who have fought their emotions all their lives and more begins to heal than just Lucas’s broken body. But just when they start to believe they could find some kind of happiness, the past rears its ugly head and Lucas will have to choose between the life he once led and the woman who has changed his world.
