The Library Trilogy - The Book That Held Her Heart (The Library Trilogy, Book 3)

By Mark Lawrence

The final volume in the The Library Trilogy, following THE BOOK THAT WOULDN’T BURN and THE BOOK THAT BROKE THE WORLD.

The secret war that defines the library has chosen its champions and set them on the board

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, family, and the world 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 bring them together 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.

Praise for Mark Lawrence -

‘An excellent writer’ -

George R.R. Martin, #1 SUNDAY and NEW YORK TIMES bestselling author of GAME OF THRONES -

‘Dark and relentless…A two in the morning page turner. Jaw-dropping’ -

Robin Hobb, the NEW YORK TIMES bestselling author of THE ASSASSIN’S APPRENTICE -

‘Excellent - on par with George R.R. Martin’ -

Conn Iggulden, author of GENGHIS -

'The Library Trilogy is one of the most profound and wholly original works of fiction that I’ve read in the past two decades. The Library Trilogy should place Mark Lawrence’s name in the same breath as other twenty-first century masters of speculative fiction' -

John Mauro -

‘Mark Lawrence gets better with every book. It has a drive to it, a pulse, a gearshift that kicks higher and higher.’ -

Fantasy Book Review -

‘This tale of knowledge and its cost flies by thanks to the gripping mystery and beautiful worldbuilding…readers will be desperate for more.’ -

Publishers Weekly -

‘Lawrence works with many threads here, but none feels misused or insufficiently explored. Rather, the author unspools them masterfully, leaving behind a tightly woven tapestry that readers will ache to see finished even if they can predict one or two of the tale’s myriad twists and turns. Gripping, earnest, and impeccably plotted.’ -
