Sydney is falling. Under a storm-lit sky, a feral she-wolf queen commands the horde while her hulking direwolf champion stalks the quay. From the black water rises Gallus-the beaked, many-limbed demon of the deep-curling around the Opera House as if claiming a throne. Across the burning city, unlikely allies converge. Jake Michaels, bruised but unbroken, refuses to retreat. Jane-no longer just the girl he saved, but the hidden Guardian of the Light-carries a power the monsters fear. Scientist Brooke Mitchell of the research ship The Talamane has a history with Gabe, once defeating the demon Gallus with a desperate plan. Gabe Mitchell knows what it costs to face Gallus-and what it costs to survive him. From a cursed mirror and a forgotten labyrinth, and a three headed dog others answer the call. Their only hope is a run in the open, straight through Circular Quay to the Opera House steps. The enemy wants dominion. The city wants a miracle. And salvation will demand a price none of them are ready to pay. When worlds collide, someone must be sacrificed. A blistering crossover of monsters, myth, and heart, Worlds Collide: The Sacrifice delivers one night of impossible choices-for a city, for a family, and for the soul of the world.
