Precise to a fault, Sage plans everything—meetings, meals, and sex. But when she learns her youngest sister can't carry a child, she steps up and commits to the role of a surrogate mother. It's not out of sentiment, because Sage doesn't do love or touchy-feely, but out of practicality. She doesn't plan on marrying or having children, so why not rent out her unused space, right?

Luke Riley's morning gets a little brighter when he's called to a clinic and spots a blonde beauty wearing killer red boots. Though she doesn't seem interested, he manages to introduce himself. It's unusual for a woman to push away his advances, but Luke is attracted to her confident nature and strong personality. It's not long before he wears her down, and she finally agrees to a date.

Sage blames her growing affections for Luke on pregnancy hormones. But one last hurrah before her belly swells sounds like a well-deserved thrill. After a few passionate nights, the line between love and lust begins to blur—leaving her more confused than ever.

Will Sage's surrogacy unlock her willingness to commit? Or will Luke stand by as the woman he loves plans a future without him?
