She was the only woman in Venice who knew the secret...and it made her a criminal.

The Murano glassmakers of Venice are celebrated and revered. But now three of them are dead, killed for attempting to leave the city that both prizes their work and keeps them prisoners. For in the 17th century, the secret of their craft must, by law, never leave Venetian shores. Yet there is someone who keeps the secret while defying tradition. She is Sophia Fiolario, and she, too, is a glassmaker. Her crime is being a woman.

Sophia knows her family would be crushed by scandal - or worse - if the truth of her knowledge and skill with the glass were revealed. But there has never been any threat...until now. A wealthy nobleman with strong connections to the powerful Doge has requested Sophia's hand in marriage, and her refusal could draw dangerous attention. Yet to accept, to no longer make the glass, would devastate her. If there is an escape, Sophia intends to find it.

Between creating precious glass parts for one Professore Galileo Galilei's astonishing invention and attending lavish parties at the Doge's Palace, Sophia crosses paths with influential people, including one who could change her life forever. But in Venice, every secret has its price. Soon, Sophia must decide how much she is willing to pay for her family, the glass, and love.
