The Somnian Veil - Sleep Nexus

Beneath Houston, the Circle guards humanity from threats hidden beyond reality itself. But when a rogue artifact unleashes the Sleep Nexus, nightmares spread through the sleeping city like a psychic contagion, turning human minds into conduits for terror. As reality blurs and dream logic invades the waking world, the Circle must descend into a collapsing subconscious realm and sever the bridge between nightmare and reality before the city falls asleep—and never wakes again.
