Helia has served as the Sage of Hope for the Great Library of Tomorrow for centuries. She is one of the chosen few who embody and protect the values of humanity across the numerous realms of Paperworld, which are connected within the Library itself via magical Portals controlled by the Book of Wisdom.

But even her hope is tested when she and her partner Xavier, the Sage of Truth, are attacked while visiting the famous Rose Garden in the realm of Silvyra. Wounded and in shock amidst a storm of fire, they are confronted by a deadly figure known to them as the Ash Man. With the Garden destroyed and its dragon protector missing, Xavier sacrifices his life so that Helia can return home to warn the other Sages.

But there she finds the Book of Wisdom—always a guide to the Sages—eerily silent. With the Ash Man gaining strength, Helia soon finds herself in a race against time, searching for clues to the origins of their foe—and any possible way to defeat him.

Fueled by the same collaborative heart and boundless imagination that dazzle millions of devoted Tomorrowland followers and festivalgoers every year, The Great Library of Tomorrow is perfect for fans of The City We Became by N. K. Jemisin and Brandon Sanderson’s Mistborn.
