A scientist injected himself with vampire bat DNA. He didn't die. He changed.Deep beneath London, inside a classified facility known only as The Vault, Dr. Grant Reid and his wife Dr. Evelyn Reid are part of a secret government project splicing animal DNA into human subjects. The goal: build the ultimate biological weapon.
When Grant injects himself with an untested serum to sabotage the program from within, he vanishes overnight. His ID badge is found melted at the edges. Security footage goes dark for exactly thirty-three seconds. And one by one, the staff who worked alongside him start disappearing into the walls.
Evelyn refuses to believe he's dead.
But what she finds is worse.
Claw marks gouged into ceiling vents. Messages scratched into steel in backward letters. Blood samples that pulse like a heartbeat. And a voice in the ducts that whispers her name.
The government wants him erased. The military wants him weaponized. Evelyn wants him back. But the thing crawling through the dark may no longer be the man she married - and the secret project he tried to destroy is bigger, older, and more dangerous than either of them knew.
Now Evelyn must outrun a kill order, decode her husband's hidden research, and answer the one question no one else will ask:
Can the man inside the monster still be saved?
