I live on pain . . . but for her, I only want to cause pleasure. Penelope: One minute I'm conducting important research on a distant planet, and the next, I've fallen through a crack in the surface and am transported to an underground world with terrifying fanged creatures who want to eat me, an army of feathered warriors who rescue me, and a massive horned demon leader who gains power through pain . . . except he's only giving me pleasure. He wants to keep me, and I have to admit, I don't hate the flaming underworld anymore. But I can't stay—my air filter will only last so long down here, and as for my demon? He can't survive on the surface. We are from two different worlds that never should have collided . . . what kind of future is there for a hot, alien demon and a human woman?
