Twenty generations ago, the Sun burnt the Earth. Men have been walled in ever since. Until a kid finds the truth.

In a world where sunlight is forbidden and truth is heresy, one young man's curiosity will either liberate humanity - or destroy everything he loves.

For twenty generations, humanity has hidden in viewless corridors, told that the Sun above has burned all life from the Earth. Boz has never questioned the Tenets that govern every aspect of their existence - until he meets Mozart the Heretic, whose disfigured face tells a different story about what really happened to those who sought the truth.

When Mozart reveals that the surface world still thrives in secret paradise, Boz faces an impossible choice: remain safely ignorant in his prison, or risk everything to discover what lies beyond the forbidden exits. Driven by his love for Flox, a remarkable young woman from the violent outer corridors, Boz embarks on a perilous journey through pitch-black tunnels toward the mythical 'Land of Without' for a mission as yet unknown to him.

What he finds shatters everything he believed. The surface world is not only habitable but beautiful - a garden paradise where the privileged few enjoy nature's bounty while millions remain trapped below in ignorance. But when Boz learns the true, appalling content of his mission outside, he must choose between the liberation of his people and the virginity of his own conscience. In a world where every freedom demands a sacrifice, how do you choose between love and justice - especially when you're no longer sure which is which?
