Pride often goes before a fall, but sometimes that prideful fall is so catastrophic that it changes history itself. Among the immortal Sithi of Osten Ard, none are more beloved and admired than the two sons of the ruling family, steady Hakatri and his proud and fiery younger brother Ineluki – Ineluki, who will one day become the undead Storm King. The younger brother makes a bold, terrible oath that he will destroy deadly Hidohebhi, a terrifying monster, but instead drags his brother with him into a disaster that threatens not just their family but all the Sithi – and perhaps all of humankind as well. Set a thousand years before the events of Williams’s The Dragonbone Chair, the tale of Ineluki’s tragic boast and what it brings is told by Pamon Kes, Hakatri’s faithful servant. Kes is not one of the Sithi but a member of the enslaved Changeling race, and his loyalty has never before been tested. Now he must face the terrible black dragon at his master’s side, then see his own life changed forever in a mere instant by Ineluki’s rash, selfish promise. Kes and his master will range the world, risking countless dangers and meeting both mortals and immortals of many kinds as they try to undo the tragedy that springs from Ineluki’s fatal pledge. During this journey, the seeds are planted for events that will culminate centuries later in the Storm King’s War in Memory, Sorrow, and Thorn and the dreadful Norn Queen Utuk’ku’s assault on humanity in The Last King of Osten Ard. In the end, Pamon Kes must question everything about his life – and risk everything, too – as he struggles to save his beloved master, Hakatri. But will anything Kes does be enough? Or has Ineluki’s rash promise already set the entire world on an unstoppable course toward destruction?
