Brilliant, free-spirited Roxie Revito wants a baby and she wants Rhyder Remington's DNA to get it. The man might be uptight and way too conservative, but he has an IQ that equals hers.

Rhyder's not interested in the over-opinionated, pint-sized dynamo with too much attitude until she turns clinical on him and cites his duty to procreate genius. Of course, she's thinking invitro... of course, he's not...

Desperate for a child, Roxie agrees to a proposed "arrangement" that includes a massive spreadsheet with formulas, schedules, and probabilities that calculate the best and quickest chance to reach her goal.

But neither has calculated the heat and desire they'll generate with their "togetherness" and that threatens the perfect deal.
