Vance Hadrian has led his research team through a rift at the bottom of the ocean-a shimmering, unnatural doorway between worlds. On the other side lies Earth 856, a savage mirror of our own. Vance says they're here for answers. But the truth runs darker than his crew suspects. He's haunted-by the day Kaiju emerged, by the destruction they left behind, and by the terrifying potential they revealed. Vance doesn't want answers-he wants to control them. To bend one of these living weapons to his will.
