Returning triumphantly to the brilliantly evoked near-Renaissance world of A Brightness Long Ago and Children of Earth and Sky, international bestselling author Guy Gavriel Kay deploys his signature ‘quarter turn to the fantastic’ to tell a story of vengeance, power, and love.  

On a dark night along a lonely stretch of coast a small ship sends two people ashore. Their purpose is assassination. They have been hired by two of the most dangerous men alive to alter the balance of power in the world. If they succeed, the consequences will affect the destinies of empires, and lives both great and small.  
One of those arriving at that beach is a woman abducted by corsairs as a child and sold into years of servitude. Having escaped, she is trying to chart her own course—and is bent upon revenge. Another is a seafaring merchant who still remembers being exiled as a child with his family from their home, for their faith, a moment that never leaves him. In what follows, through a story both intimate and epic, unforgettable characters are immersed in the fierce and deadly struggles that define their time.  
All the Seas of the World is a page-turning drama that also offers moving reflections on memory, fate, and the random events that can shape our lives—in the past, and today.
“Tragic, stirring, romantic, meticulous, comic, rueful, worldly-wise, and written in the intimate, deceptively nonchalant voice of a storyteller offering up his great gift, All the Seas of the World is classic Kay, and to this reader, at least, there can be no higher praise.”
—Michael Chabon

“A compelling historical fantasy, [All the Seas of the World] develops with the creeping intensity of an avalanche: an action here, an assignation there, and before you know it, all hell has broken loose. It’s a thrilling and exciting reading experience. . . . Written largely during the pandemic [the novel] has an elegiac quality, an aching awareness of the temporary nature of lives, empires, worlds. As Kay writes, ‘If we take a moment for them it is also a moment taken for ourselves. For those who love us, those we love.’” —Robert Wiersema, Toronto Star

“A mosaic of captivating story lines within a mesmerizing narrative frame. . . . Kay constructs a rich world that easily draws readers in. Historical fantasy fans will be wowed.”
—Publishers Weekly (starred review)

“This is an immersive reading experience; readers will taste the dust in their mouths, see the high seas from the deck of a merchant ship, feel the bustle of the city market. What results is necessary sustenance for the starving reader. A masterpiece from a master of the craft.”
—Booklist (starred review)

“Meticulously crafted in structure, pace, language, dialogue.... but crafted not just with skill but with heart ... so one is both saddened and gladdened in turn, moved and inspired throughout.”
—Fantasy Literature

"All the Seas of the World is as rich a tapestry as we've come to expect from Kay—perhaps one of the richest."

"All the Seas of the World is a story of resilience winning out, of . . . individuals finding a way to vanquish their demons in spite of all the powers arrayed against them. [Kay is a] master of telling small stories in a big world." 
—BookPage (starred review)
