The second book in Alexander Gordon Smith's no-holds-barred teen series, where the terror has only just begun - now with the bestselling US cover.

We thought we'd made it, we thought we were free. But we should have known there was no way out of Furnace.

All we did was slip deeper into the guts of the prison: into solitary confinement, where the real nightmares live - the warden, the Wheezers, and something much, much worse.

The clock's ticking. Because if we don't escape soon they will turn us into freaks - like them. Forever.

In the darkness of the hole your worst nightmares come to life...

Action-packed, gritty and gruesome - this is the perfect read for thrill-hungry teenagers.
