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.
