Fantasy novelist Jillian Jones-Jenkins always stays in the house. She hasn’t had a single romantic encounter in the past thirty years, and she’s never been in love. Her friend Andrea is worried about her and assigns her brother Forrest as a “trial horse” so Jillian can find out what love is like. Jillian is a dreamer, who always lives in a fantasy, while Forrest is an A-list celebrity and a realist. They live in very different worlds. But that isn’t the only problem—Jillian has yet to find out that her romantic meeting with Forrest was all a setup!
