The discovery of a secret baby threatens Caleb's professional reputation. Falling for the woman who loves this baby would ruin him. Marriage therapist Caleb Paden has just found out he has a son from a one-night stand, making a mockery of his core belief of stable relationships—“friendship above all physical encounters.” On his way to take the child for a paternity test, a snowstorm leaves him stranded with single mom Olivia Wells, who blames his advice for breaking up her marriage. Caleb finds himself fighting the urge for the most basic of physical encounters. Olivia would like nothing more than to destroy the career he spent a lifetime building, but her maternal instincts draw her to help Caleb bond with his child. Soon, she finds herself falling for both of them. Nowhere in any of his advice does Caleb have an answer for how to make a relationship work if he loses his heart to love.
