Alessandro Santini, an Italian doctor from the twenty-first century, lives an ordinary life in modern day Florence. But one evening, he passes through a swirling vortex caused by a supermoon and discovers he has stepped three hundred years into the past. Countess Rose Estes is torn between following her dream of becoming a historical painter and her duty toward her family.
After Rose’s father is wounded during her birthday ball, Alex and Rose burn with questions: Who attacked him with a flying dagger? Why? Forced to go to Siena and spend fourteen months together, Rose and Alex find themselves drawn to each other as they search for answers and discover secrets that go deeper than they ever imagined. As the portal’s opening approaches, Alex finds out that Rose has been poisoned through the roses she’s been receiving. He has two choices to save her life—take Rose to his time or go by himself and bring the medication she needs.
