Is this Heaven . . . or Hell?

Estranged identical twins Daniel and Max have a complex relationship, so when Daniel goes to visit his bi-polar brother in a remote and expensive Swiss ''recovery'' clinic, he has no idea what really lies in wait for him.

Lulled by the routine and peacefulness of the clinic, Daniel finds himself unquestioningly accepting Max's plea for help in taking care of some business, and the brothers swap places for a few days.

But soon Daniel realises Max isn't coming back, and that the clinic is far from a place of recovery. Struggling to get anyone to believe who he really is, Daniel finds himself trapped in a cruel and highly secretive prison: this is no sanctuary, it's a living nightmare . . .

With the atmosphere of Shutter Island and the intensity of Jussi Adler-Olsen, immerse yourself in this relentlessly compelling psychological thriller from one of Sweden's bestselling crime authors.
