After Nightland’s vicious attack on the domes, the safety and perfection of the world within the glass has been contaminated. Desperate to rebuild, outsiders are allowed into the domes to help, breaking the cardinal rule: outsiders and Domers must always be separated. But the city is in shambles, crumbling into chaos without the Vampers of Nightland to keep order, and one name is carried on the wind: Nola.

Clinging to Jeremy, Nola struggles to find a way to exist in the domes, turning her back on all she learned in the city. But when one of the outsiders brings the dark secrets of the domes to light, the line between survival and murder blurs against the spectre of the dying world.

Can Nola follow the dark path laid out by the Domes? Will the dangers of the night become her new sanctuary?
