One With the Darkness (Companion, #6; Da Vinci Time Travel, #1)

Contessa Donnatella di Poliziano has power, beauty, and--as a vampire--eternal life. Her overwhelming regret is a mistake she made centuries ago when she chose not to transform her one true love, Jergan, into a vampire too. Donnatella's choice has deprived her of the only true love she's ever known. But just as all seems lost, the discovery of a 300-year-old note leads her to a gift left by her old friend, Leonardo da Vinci: a machine to take her back in time to rewrite the history of her heart ... Once back in time, Donnatella's memory of the intervening years is lost. Yet when she sees the breathtaking Jergan from afar, she feels like she has always known him. The instant attraction she feels draws them together. For Donnatella, the romance is tantalizing, awakening a passion that feels both old and new. But as the two fall in love again, a new danger threatens to tear them apart. Now Jergan's love for Donnatella will be tested in a most perilous way--and if he fails, the two lovers will be separated again ... for eternity Over numerous centuries, Contessa Donnatella di Poliziano has bitterly regretted following the vampire rule that forbade the making of a new vampire. Because of that edict, Donnatella lost the only man she ever loved, Jergan. Now a long-hidden note from her good friends Michelangelo and Leonardo lead Donnatella to a time machine and a second chance. She steps back in time to the Roman Empire, where she was once Livia Quintus Lucellus. But upon her return, Donnatella becomes Livia -- without the memories of why she returned. As part of the movement to remove Caligula, Livia's in jeopardy, but it is buying a slave named Jergan that initiates fateful events. Only her dreams give Livia clues about the treacherous dangers ahead "Contessa Donnatella di Poliziano has power, beauty, and--as a vampire--eternal life.
