The sixth installment in Jasper Fforde's New York Times bestselling series follows literary detective Thursday Next on another adventure in her alternate reality of literature-obsessed England-from the author of Early Riser

Dazzlingly funny and imaginative, Jasper Fforde's books have won him the affection of readers, reviewers, and-dare we say it-booksellers alike. Fans can breathe a sigh of relief because Thursday Next-or at least one of her-is back. At a time of great unrest in the BookWorld, only the ace literary detective can avert a devastating Genre War-thing is, Thursday has vanished. Now the written Thursday must answer the call, save the Bookworld, evade capture, and find the actual Thursday! With a clockwork Butler in tow, and Men in Plaid as well as her Designated Love Interest in pursuit, she must reluctantly agree to journey up the mysterious Metaphoric River for answers.
