The Fragile Threads of Power

The Fragile Threads of Power, written by the #1 New York Times bestselling author of The Invisible Life of Addie LaRue and set in the world of A Darker Shade of Magic, provides a new portal into dangerous exploration and intricate plots.

There once were four universes, tucked inside one another like pages in a book, all pulsating with magical force and joined by London. Up until the magic developed too quickly, forcing the worlds to wager desperately to defend themselves by sealing the doorways between them. With time, the few magicians who were still able to open the doors became increasingly few, and as of right now, just three Antari are known to exist: Holland Vosijk of White London, Delilah Bard of Grey London, and Kell Maresh of Red London.

However, in the past seven years, there has been hardly any sight of them, and Kosika, a new Antari, has emerged in White London to usurp Holland's crown. The young queen is prepared to use human blood, even her own, to feed her people, but her increasing religious zeal runs the risk of drowning them.

Returning to Red London, King Rhy Maresh faces a growing uprising that intends to overthrow the monarchy in order to restore the proper balance of power.

A girl with a strange magical talent finds herself in control of a gadget that has the power to alter the course of all four worlds amid this patchwork of enduring friends and brand-new foes.

The only person who can unite them—or piece everything together—is Tes.
