When American librarian Samantha Lewis and Irish rogue Keirnan Fitzgerald set off to find priceless jewels, they become embroiled in a 500-year-old love story that eerily prefigures their own...

In 15th century Venice, beautiful and wealthy Serafina falls in love with Nino, a young Florentine sculptor. They decide to flee to Padua, and to fund the trip, Nino copies a set of jewels that then disappear.

In modern-day Venice, Keirnan needs Samantha's help to locate the jewels so he can pay his sister's ransom. Samantha must decide whether the man she's so drawn to is her soul mate from a previous life...or are they merely pawns in a relentless quest for a priceless treasure?
