When David Kinder agreed to lead the Whisper King's army into war, he was promised answers to all of his questions. That included "the knowledge that burns." But this truth may even be too much for the Prince of the Shadow Mountains, for mortal and immortal alike have succumbed to the madness it ignites. Even as David wrestles with matters of the mind and spirit, a physical threat looms in the form of the Amathair, a homicidal creature from the end of time. With thousands upon thousands of skeletal Dearmad troops at its command, the Amathair threatens to annihilate all of reality. Only monsters stand against this threat. And only David Kinder, heir to the Whisper King, can lead them to victory...or damn them to ruin.
