From the back cover:
Stranded in the present, time traveler Caleb Hornblower's biggest problem isn't returning to the twenty-third century—but falling head over heels for the beguiling Liberty Stone, who shows him a love more powerful than time itself. Though Caleb knows he belongs in the future, how can he leave the past, and Liberty, behind?
Cynical Jacob Hornblower has followed his brother, Caleb, back in time, hoping to convince him to return home. His mission is soon forgotten, however, when he finds himself captivated by Liberty's spitfire sister, Sunny. But can a man who is down on love truly understand the unbounded strength of the human heart?
