Irish Whiskey by Jen Talty

Irish Whiskey left his cousins farm years ago to join the Army and he never looked back. That was until he gets a phone call from one of his relatives informing him that one of the many broken hearts he left behind showed up at Whiskey Ranch claiming to be carrying his child.
And she won’t leave until he comes back and decides if he wants to be a father, or he’s going to do what he’s always done—run from his responsibilities.
Lorelei Sheldon knew the second the sexy Special Forces officer walked into her diner she was in trouble. But she hadn’t expected it to be the kind of trouble that would change the course of her entire life. With no way of reaching him, except through his family’s ranch in Buhl, Idaho, Lorelei packs up her things and sets off to find the man who she knows without a doubt she wants to start a life with, but also understands he might want nothing to do with her.
But she has to try. She owes it to their unborn child.
