The gripping finale to the international bestselling Mirror Visitor saga. “A hallucinatory marriage of Pride and Prejudice and A Game of Thrones.” —Matthew Skelton, New York Times–bestselling author Christelle Dabos takes us on a journey to the heart of a great game to which the all-too-human affairs of her book’s protagonists are ominously connected. The distrust between them has been overcome and now Ophelia and Thorn love each other passionately. However, they must keep their love hidden. Only in this way can they continue their journeys toward an understanding of the indecipherable code of God and the truth behind the mysterious figure of the Other, whose devastating power continues to bring down entire pieces of arks, plunging thousands of innocents into the void. Ophelia and Thorn arrive at the observatory of the Deviations, an institute shrouded in absolute secrecy and overseen by a sect of mystical scientists who secretly conduct terrifying experiments. There, Ophelia and Thorn hope to discover truths that will halt the destruction and death and bring the world back into balance. “Metaphysical mystery, compellingly in the wings for most of the series, takes center stage in the quartet’s final installment.” —Kirkus Reviews “A series founded on political intrigue and romance has made a hard pivot into the nature of identity, agency, and sacrifice as these characters fight for their happy ending.” —School Library Journal “Utterly extraordinary books . . . The Storm of Echoes and the Mirror Visitor series [are] the Alice Through the Looking Glass of our time.” —Quaere Living
