Sleep tight. We're always listening.

Arthur Winter's job at the Ministry of Detection used to be simple: track down the humanoid alien hybrids and lock them up. But after a botched operation, he finds himself on a different kind of assignment. One that's off the books and very hush-hush.

Mary Haddon, eminent scientist and daughter of a senior politician, is missing and its Winter's job to find her.

But when Winter discovers Mary's history of communication with illegal alien hybrids, he realises that his assignment is about more than just a missing woman. As he gets deeper, he finds questions going in every direction.

If Mary ran, who is chasing her? Why is her disappearance a matter of secrecy? And what is Project Cocoon?

The only thing Winter knows for sure if this is definitely above his pay grade.
