The Book That Wouldn't Burn

Book 1 of 3 listed

Released on 9 May 2023

Two strangers find themselves connected by a vast and mysterious library containing many wonders and still more secrets, in this powerfully moving first book in a new series from the international bestselling author of Red Sister and Prince of Thorns.

Rest of description

The boy has lived his whole life trapped within a book-choked chamber older than empires and larger than cities.

The girl has been plucked from the outskirts of civilization to be trained as a librarian, studying the mysteries of the great library at the heart of her kingdom.

They were never supposed to meet. But in the library, they did.

Their stories spiral around each other, across worlds and time. This is a tale of truth and lies and hearts, and the blurring of one into another. A journey on which knowledge erodes certainty and on which, though the pen may be mightier than the sword, blood will be spilled and cities burned.

Two people living in a world connected by an immense and mysterious library must fight for those they love in the second book in a new trilogy from the international bestselling author of The Book That Wouldn’t Burn.

Rest of description

The Library spans worlds and times. It touches and joins distant places. It is memory and future. And amid its vastness Evar Eventari both found, and lost, Livira Page.

Evar has been forced to flee the library, driven before an implacable foe. Livira, trapped in a ghost world, has to recover the book she wrote—one which is the only true threat to the library’s existence—if she's to return to her life.

While Evar's journey leads him outside into a world he's never seen, Livira's path will taker her deep inside her own writing, where she must wrestle with her stories in order to reclaim the volume in which they were written.

The secret war that defines the library has chosen its champions and set them on the board. The time has come when they must fight for what they believe, or lose everything.

The Book That Held Her Heart

Book 3 of 3 listed

Released on 8 Apr 2025

Two people once connected by a vast and mysterious library are now separated and must overcome time and distance to reunite and bring peace to their worlds, in the final book of the Library Trilogy.

Rest of description

The fate of an infinite library hangs on one book, a book that holds the power to break the unbreakable. In the face of such forces, fragile things like hearts, worlds, and even family seem certain to fail.

The people most vital to Livira are scattered across time and space—lost, divided into factions, in mortal peril. Somehow she must bring them together and resolve the unresolvable argument that fuels the library’s war.

The bond between Livira and Evar has stretched and stretched again. Can it hold at the end, when things fall apart? Can it unite them against impossible odds?

This is the last chapter, the final page. The end threatens and no one—not characters, readers, or even the author—will emerge unscathed.
