Discover the magic of the doormakers and begin an epic journey of secrets, betrayal, and power. THREE WORLDS. ONE RULE. SHE MUST NEVER OPEN A DOOR. Since before Maella can remember, one family rule has shaped her life: never open a door. Maella comes from a family of doormakers—people who unleash otherworldly violence when they open something even as simple as a cabinet door. Maella didn’t mean to open a door. Maella tried NOT to open a door. She just wanted to save her friend. Pushed through a portal of her own making, Maella discovers worlds of nightmarish flying monsters, magical drug deals, political prisoners, religious cults, and a terrifying prediction: Maella will die upon opening her seventh door. In order to survive, Maella must uncover her family’s secrets, all while hiding her identity and outrunning the prediction of her death. But what do you do when the truth you need could destroy the universe?
