Luke Has Faith (Harper Family #5)
Judy Kay, O. L. Gregory

Anne London is new in town, and hoping to meet back up with the cute officer-in-training she’d given a black eye to the last time she was in town.
Luke Harper remembers the spitfire. Remembers, too, the make out session they had afterwards. He’s eager to pursue a relationship, even ready for a commitment. There’s just one problem, though.
In the future his mother saw, his wife’s name is supposed to be Faith.
