An expert in Leonardo da Vinci’s works, Lucy Rossano recognizes the centuries-old time machine da Vinci said he built the moment she sees it in a Stanford lab. Fascinated in spite of the danger, she uses her knowledge to go back in time—landing in the middle of a fierce battle in tenth-century Britain. Panicked, she escapes to modern-day San Francisco, bringing 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.
