After an evil warlock kidnapped his boyfriend and best friend, Mateo Álvarez-Moreno’s life is shattered, and he’ll stop at nothing to get them back. But their abduction is only the beginning. A powerful crystal has been stolen, an artifact said to grant invincibility and unimaginable strength. In the wrong hands, it could lead to the end of humanity. And Mateo suspects it’s in the hands of a billionaire hellbent on godhood. To save the people he loves—and the world—Mateo must return to the one place he swore he’d never go the infamous Red Flags mansion. Whispers say the crystal is hidden there, along with the captives he’s desperate to rescue. But the mansion holds more than secrets. It’s a labyrinth of betrayal, dark magic, and horrors that defy reason. Every second counts as Mateo battles demons, vampires, and other monsters who try to thwart him from stopping a ritual to end the world. With his friends scattered, his magic pushed to its limits, and the world teetering on the brink, Mateo has one burn it all down before it burns him.
