One brilliant scientist. One buried secret. And one virus that might save the world-or doom it. Lilly Cross has spent her life unraveling biological mysteries, but nothing could prepare her for this: alien vampires, a severed hand, and a globe-spanning conspiracy hiding in plain sight. Armed with her intellect, a few trusted allies, and a dangerous secret of her own, Lilly hatches a plan to level the playing field-by unleashing a virus tailor-made to wipe out the monsters hiding among us. But tampering with life and death comes at a cost. And as her world begins to unravel, Lilly must decide how far she's willing to go… and how much she's willing to lose to protect her family.
