All We Keep Hidden by Kristen Martin is an adult urban fantasy about Maren Cordeau, a 30-year-old karmic vigilante known as a Noire who enforces eternal justice on those who’ve sold their souls, using nightmares to punish the guilty. When a routine supply run turns into a nightmare of its own—leaving her witch mentor murdered and Maren as the prime suspect—she must revisit her past lives with her assigned protector and rival, Brant Colborn, uncovering truths that could reshape reality itself.
