Dawn’s Untrodden Green by Carolyn Miller

Not much happens in Theodosia Stapleton’s tiny Northumberland village. Certainly not to her. She has resigned herself to spinsterhood, caring for her ailing mother in the home of her grandfather, known to the locals as “General Contrary.” When her dear friend dies and leaves behind a daughter, it’s simple enough to take the child into her own quiet world. That is, until her ward’s famous uncle unexpectedly arrives and throws Theo’s tidy orbit completely off-kilter.
Fame was the last thing Daniel Balfour sought when he fought in the Peninsular War. But his brave exploits caught the attention of the King, and now the honors he was given hound him everywhere . . . even on his rushed trip to rescue his orphaned niece.
Theo’s quick wit and warm smile reassure him that Rebecca is in good hands, and he finds himself free to swiftly return to London and his responsibilities. But those caring hands are beginning to look like they could also safely hold his heart, and he’s tempted to linger. Unfortunately, marriage is simply not in the cards; the army is spouse enough for him.

Then an accident and a scandal lead both Theo and Daniel to discover that their best-laid plans may not have been what God designed for them after all.
