Deep beneath the Arizona desert lies Subterra-9, a classified government facility conducting unauthorized genetic research. Dr. Grant Caldwell and his brilliant wife Elena were part of its most dangerous experiment yet: merging human DNA with bat genomes to unlock new biological frontiers.

Then Elena vanished.

Now, something stalks the underground halls. Co-workers disappear. Systems fail. The survivors whisper about a shape in the vents-fast, brutal, and eerily familiar.

When Grant discovers Elena injected herself with the experimental strain, his mission becomes clear: find her before the government terminates her-and before her altered mind forgets what it means to love.

But what if she's already gone?

And what if something worse came back in her place?
