Metro 2033 (Metro #1) - Dmitry Glukhovsky

The year is 2033. The world has been reduced to rubble. Humanity is nearly extinct. The half-destroyed cities have become uninhabitable through radiation. Beyond their boundaries, they say, lie endless burned-out deserts and the remains of splintered forests. Survivors still remember the past greatness of humankind. But the last remains of civilisation have already become a distant memory, the stuff of myth and legend.
