His mind is a cathedral and she has the keys. Alan Thorne wakes up every day to a life of perfect order. Diana, his caretaker and lover, has stripped away the "noise" of his past to help him heal. But the healing feels like an erasure. When Alan begins to see jagged, geometric symbols glowing in the dark of his bedroom, he realizes his dreams are no longer his own. They are blueprints. With the help of Logan, a man who has already lost his soul to the sigils, and Mara, a tether to the life he was forced to leave behind, Alan discovers the truth: he is trapped in a Dreamcatcher Conduit. Diana isn't just protecting him; she is version-controlling him, deleting his flaws to fuel a ritual that will bind them forever. Sigils in Sleep is a high-stakes descent into a world where the only way to wake up is to shatter the dream from the inside out. The sequence is set. The bond is deep. But the noise is coming.
