The New York Times bestselling author of the Sea Haven novels returns to the circle of the six sisters of the heart, bound by the elements-and to one who possesses the power to inflame the most dangerous passions of all. Flame-haired Lissa Piner is a skilled glass blower whose delicate gift conceals a burning inner strength that can destroy as exquisitely as it can create. Commissioned to design chandeliers for a string of luxury hotels, her remarkable skills have taken her to Italy. But Lissa's real mission there is a secret. For her entire life has been a lie, leading to a chance to avenge a terrible wrong. Enlisted as her bodyguard is Casmir Prakenskii, a trained assassin living off the grid. In Lissa, he sees a kindred spirit-something unexpected and wicked, mysterious and sensual. But more than desire is about to bring them together: because both of their pasts cry out for revenge. And for two people with this many secrets, this much passion, and this many enemies, someone is bound to get burned.
