The first chapter of this book finds Alanna, Faithful, and Coram on a quest for the 'Dominion Jewel', which grants immense psychokinetic power to any monarch who owns it. In the town of Berat, Alanna befriends martial-arts champion Liam Ironarm, called the 'Dragon of Shang', who joins the quest. Liam begins training her in Shang fighting style, and the two become lovers. The party thence traverse the realm of Sarain, evading a civil war between the native 'K'miri' tribes and the ruler, Warlord jin Wilima, and acquire new companions in Princess Thayet, the Warlord's only child, and her K’miri protector Buriram Tourokom. At the mountain range known as the 'Roof of the World', Alanna becomes frustrated by the blizzards blocking their progress and her magical sense that trouble is occurring back in Tortall. She casts a spell on the group to keep them asleep and then ascends to the pass, where she undergoes a grueling physical trial to acquire the Jewel from its immortal guardian, Chitral. She succeeds in winning the Jewel and returns to the group, to find that Liam—who is afraid of magic—is angry at being bewitched by her. Their romantic relationship ends, though they continue as friends and colleagues.

Upon their return to Tortall, Alanna is met by her old friend Raoul of Goldenlake, who informs her of three key events that have occurred in her absence: the Tortallan monarchs have died; Prince Jonathan has been named King but not yet been crowned; and Alanna's twin brother Thom, to prove himself the most powerful sorcerer in the realm, has resurrected Duke Roger (killed by Alanna in an earlier book). Alanna hurries to take Jonathan's side and give him the Dominion Jewel, and Jonathan names her as his King's Champion. Elsewhere in Corus, Thom is being rapidly poisoned by his own magic, by its interaction with that of Roger. On the eve of the Coronation, Tortall's Great Mother Goddess warns Alanna that the ceremony will be a "crossroad in time", decisive of the realm's future. During the coronation, Roger’s plan comes to fruition: he causes a series of magical earthquakes using his and Thom’s joined power to bring down the palace, while insurgents loyal to Roger and his allies Lady Delia of Eldorne, Alex of Tirragen (Alanna’s childhood friend), and Claw, aka Ralon of Malven (Alanna’s former bully) storm the palace. Jonathan uses his Gift and unleashes the Dominion Jewel’s power to keep the earthquakes at bay, while Alanna‘s friends battle to protect Jonathan from assassination and Alanna goes in search of Roger. In the prolonged battle, Thom dies, drained of his life by Roger's magic. Alanna duels Alex and defeats him. She then kills Josianne, after the princess has killed Si Cham and Faithful. Roger awaits her in the catacombs, presiding over a Gate of Idramm. He reveals how he survived his death due to Sorcerer's Sleep, as well as his hand in Lightning's origins. Weary and temporarily Giftless, Alanna remains ready for battle. Roger summons Lightning toward him, and after resisting, she realizes the benefit of having the sword fly toward him. In less than the blink of an eye, Roger is impaled by the force of the sword's movement. Alanna emerges from the battle to find in the aftermath that Jonathan and her friends survived, the insurgents are defeated and captured, but Liam Ironarm was killed defending Jonathan.

Later, Alanna returns to the Bazhir (a Bedouin-like ethnicity of Tortall's southern desert) to recover from her losses. She learns that Jonathan has married Thayet—a match Alanna had given her blessing to—and appointed George a baron to guard Tortall's coast. George arrives in the desert to seek out Alanna, who professes her mutual love for him. The two head exit the tent to tell the Bloody Hawk tribe of their betrothal.
