Tess O'Connor has never fought in a duel, ridden a Fae steed descended from a dragon, or touched taebramh, the magical substance that gives mortals dreams. She has never faced down a garrelnost or traveled the hidden mysterious pathways between the mortal world and the realm of the Fae. She has never felt a magnetic attraction to a perilously handsome Sidhe knight with eyes as deep and impenetrable as the ocean. Tess O'Connor stopped believing in fairy tales as a child when her father died...but all that changes when she discovers that her best friend Molly is half-Fae-and has been summoned to the Unseelie Court by Queen Mab herself. The Queen of Night and Winter sends Finnead, one of her trinity of Named Knights, to escort Molly to Court, willingly or unwillingly. Mab believes that Molly is the fulfillment of a prophesy, the half-Fae child foretold to become the bearer of the Iron Sword, a legendary weapon that could mean the difference between victory and defeat for the Fae in their struggle against an ancient evil. While Tess quickly learns she is no match for the shadow spreading through the Fae world, she refuses to let her best friend face it alone; and as the first mortal in Queen Mab's court in over five hundred years, she must use all her quick wit and tenacity to keep herself and Molly alive in the beautiful, dangerous Fae world as they hurtle toward the war that could destroy it...
