The Absolute Book by Elizabeth Knox
An epic fantasy about ancient treacheries that span worlds, a mysterious scroll box that has survived centuries of fire, and the undying power of stories.
Taryn Cornick believes she has put her sister's violent death and her own complicity in an act of retribution behind her. But her successful book about the perils that threaten libraries mentions an ancient scroll box--called the Firestarter--that has inexplicably survived numerous fires, including one at her own grandparents' estate, and now powers in both this world and beyond are looking for her.
DI Jacob Berger has questions about Taryn's past and his dogged interest means they both suddenly find themselves in a mysterious land of peace and plenty, carried there by a shadowy young man named Shift. The land, home to a beautiful people who long ago bargained a terrible price for their idyllic existence, is now threatened from the precincts of Hell itself, and Taryn is of great interest to the rebels. But Shift is key to both the unimaginably precious scroll inside the Firestarter and to the outcome of the threatened war, and he has an ambitious plan of his own.
The Absolute Book is a sweeping novel of journeys and returns, from contemporary England to realms beyond ours, from New Zealand to Purgatory itself, intimately weaving together the stories of vivid characters who face a reckoning that could change the future of all of these worlds.
