The Counterfeit Husband. Rigsby, #8

A girl raised in a series of foster homes is sent out at eighteen to fend for herself. She meets a soldier who says he understands how that must feel. Unknown to her, he was raised the same way. But he doesn't tell her that. Instead he borrows the story of a man he met in basic training.  They two are lonely and marriage for what they think is love with is not really. When Aaron dies overseas, Julie decides to move to his hometown, Rigsby, Wyoming.
She does wonder why none of his family comes to his funeral. Still, she hopes the family will accept her daughter, if not her. When she arrives in town, she cannot find the family that Aaron told her so much about. But news of someone new in town gets around so that the man whose life Aaron said was his life gets back to hi,. He has to tell the lady the truth. Even so he feels for her and his mother goes wild over the little girl.
Though she has a hard time believing that Aaron talked about Alex's life instead of admitting he was a foster kid, too. Can Alex understand that she fell in love with him while thinking it was Aaron?
