Seven strangers - each with a unique skillset but with no memories of their respective pasts - must undertake a terrifying journey into the heart of darkness.

A man awakes on a boat at sea with no memory of who or where he is. He's not alone - there are six others, each with a unique set of skills. None of them can remember their names. All of them are armed.

When a message appears on the onboard computer - Proceeding to Point A - the group agrees to work together to survive whatever is coming.

But as the boat moves through the mist-shrouded waters, divisions begin to form. Who is directing them and to what purpose? Why can't they remember anything?

And what are the screams they can hear beyond the mist?

Internationally bestselling fantasy author Anthony Ryan - writing as A. J. Ryan - delivers a nerve-shredding thriller in which seven strangers must undertake a terrifying journey into the unknown.
