Two worlds. One glass wall. No turning back.

The human race has been divided. The chosen few live in the safety of the domes, watching through their glass walls as those left on the outside suffer and die. But desperation has brought invention. New drugs have the ability to alter humans, giving them the strength to roam the poisoned night unafraid—but survival comes at a terrible price.

Seventeen-year-old Nola Kent has spent her life in the domes, training to protect her little piece of the world within the glass. The mission of the domes is to preserve the human race, not to help the sick and starving.

When the fate of an outsider child falls into her hands, Nola dares to venture beyond the security of her home, diving into a world of darkness and vampires. Life within the glass didn't prepare her for the realities of suffering or the depth of forbidden love.

When blood washes over the domes, Nola must choose between her home and her heart.
