She only has to pretend to be married for five days. What's the worst that could happen?

Literature professor Ashleigh Darmody never imagined her life would turn into a classic trope, but that's exactly what happens when her sister Claire calls with a bizarre request--quickly find a fake husband. Backstory is a powerful thing, and Ashleigh's has plenty of shadows, but is her past so shady that it requires an elaborate scheme to ensure Claire's prospective father-in-law, renowned TV evangelist Ken Abrams, will give her his blessing to marry his son?
Already divorced from a man who turned out to be other than he claimed, Ashleigh now has to pretend to be blissfully married to a stranger for the next five days. But when the lines of fiction and reality blur with each tick of the clock, could a temporary deal turn into something for keeps?
