**The #1 *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 Casimir 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.
