"A wondrous lucid dream...laced with a vivid sensuality." —Jacqueline Carey, New York Times bestselling author of Kushiel's Dart  A talented heretic must decide between the pursuit of forbidden magic, or the ecstasy of forbidden love, in the start of a sweeping, romantic epic fantasy trilogy by New York Times bestselling author Tessa Gratton.Can an empire trip and fall on a mere strand of silk?  Iriset is a prodigy and an outlaw. The daughter of a powerful criminal, she dons her alter ego Silk to create magical disguises for those in her father’s organization, but she longs to do more with her to enhance what it means to be human by giving people wings, night-sight, and other abilities; to unlock the possibilities of gender and parenthood; to cure disease and even to end mortality itself.   Everything changes when her father is captured and sentenced to death. To save him, Iriset must infiltrate the palace and the empire’s fanatical ruling family. There, she realizes she has a chance—and an obligation—to bring down the entire corrupt system. She'll have to entangle herself in the lives of the emperor and his sister, getting them to trust and even to love her. But love is a two-way street, and Iriset’s own heart holds the most mysterious and impenetrable magic of all. ★ "A beautiful, elegant, passionate novel—as intricate and beguiling as a spider's web. A triumph and a delight from start to finish." —Antonia Hodgson, author of The Raven Scholar  ★ "Expertly balances one of the coolest magic systems of the decade, twists that had me gasping out loud, gloriously messy relationships, and the soaring ambition of the architectural genius at its heart.
