An Officer's Vow by Penny Hampson

Nate was injured in the war and as he heads home, he feels he has nothing to live for.  He's not much of a man anymore since his leg gives out on him, and he doesn't want his father to feel pity for him.  While he's wallowing in these bad thoughts, his horse suddenly spooks and he manages to lose his seat and, of course, he falls on his bad leg.  As he tries to recover from the fall, he finds a young female attempting to care for him.  It seems she was in the bushes and spooked the horse and she's worried she injured him.  He tells her it was a war injury and if she helps him get up he'll continue his journey.  He asks why she's out there all alone.  She tells him and he takes her with him...

BooksGoSocial and Net Galley gave me the opportunity to read this book for review (thank you).  It has already been published.

It seems Lottie's father has died and the boy she was hoping to marry died in the war, so his younger brother intends to marry her and then steal all the money her father left her.  He's distasteful, grabs parts of her body, and then she finds he plans to sell her to a brothel to get rid of her.  So she runs.

Nate intends to keep her safe.  He can't do that too well with a bad leg but he can take her home and with his father and the staff she will be protected.  That's if they make it there.

The rejected suitor is after her so he can have her money.  If they weren't having enough trouble hiding, the Duke gets  involved and his help leads them into a dangerous situation.  They've become a team.

I enjoyed this story.  It has lots of adventures, the Duke is almost more of an enemy than a friend and the romance bounces back and forth.  Neither one has said they love the other so it gets all confusing.  But it ends well.  For a while there, I wasn't sure...
