In present-day Boston, Nina Revskaya, once a great star of the Russian ballet, has decided to auction her jewellery collection and donate the proceeds to the Boston Ballet Foundation. It is a mysterious gesture that has piqued the interest of two particular individuals: a rising associate director at the auction house, Drew Brooks, who seeks to unravel the provenance of the pieces; and a professor and Russian translator at the nearby university, Grigori Solodin, who believes the jewels might hold the key to his past. The stakes are raised when an anonymous individual donates a necklace that perfectly matches the bracelet and earrings in Nina's collection, claiming the pieces belong together. It is this donation that will bring Drew and Grigori together in unexpected ways to uncover the story behind Nina's fabulous jewels--a bounty said to have been smuggled out of Stalinist Russia when she defected from the country in the early 1950s. It was there, in Russia, that Nina first learned to dance, fell in love with the handsome poet Viktor Elsin, and struggled with the choice to pursue her craft or begin a family. Nina and her circle of free-thinking artist friends lived in constant fear of Stalin's disapproval, of arrest and torture by the secret police for unpatriotic behaviour and so-called crimes against the state. Yet when their circle was broken by just such an arrest, a devastating misunderstanding parted the four friends and lovers forever.
