Damaged Hero by Jo Grafford

He has a checkered past to overcome. She has a baby on the way. When tragedy strikes, all they have left to cling to is God…and each other!

Foster Kane is an all-in kinda guy. He’s partied hard, spent a few years in the pen, and is now working like crazy to make up for past wrongs. When he lands a job at Anderson Ranch, things are finally looking up. But his older brother is home from the Marines so messed up in the head that he can barely take care of himself, much less his new wife and the baby they have on the way. Foster steps in to help and soon finds his loyalties torn between his brother and the spirited mother-to-be his brother never got around to legally marrying.
Shayley Neeson is a penniless orphan, raised by an older sister who eventually left her, too, when she enlisted in the Marines. And now she’s married to one of her sister’s comrades-in-arms who claims a piece of paper won’t make them any more married. The only person she’s ever been able to count on — no matter what — is her rebel brother-in-law. A guy everyone else thinks is damaged…
When danger comes knocking, Foster proves yet again that he’s the one constant in Shayley’s life, but will he ever be more? Does a love triangle like theirs stand a chance at leading to a happily-ever-after? Can anything beautiful or good ever come from so much brokenness?
