An expert in Leonardo DaVinci’s works, Lucy Rossano recognizes the centuries-old time machine the moment she sees it in a Stanford lab. Fascinated in spite of the danger, she uses her knowledge to briefly go back in time — landing in the middle of a fierce battle in ninth-century Britain. And when she returns to modern-day San Francisco, she brings something back with her: a seductive, fiercely intelligent Viking named Galen.
The presence of this enigmatic, devastatingly sexy stranger is just one of the new complications in Lucy’s life. There are others who want to harness the time machine’s power for treacherous ends, and they need Lucy to do it. Galen becomes first her protector, then the lover she’s always dreamed of. But danger is drawing closer, and time is running out. For Galen and Lucy, it’s now…or forever.
