A frozen child is found close to death on a Cape Town mountainside. A gifted young musician leaves her school and disappears. A frightening pattern begins to emerge and Dr Clare Hart must unravel the secrets of these cases ... whilst carrying a secret of her own.

It's Rosa.
There's trees outside. Get me help.
Please.

A terrified young woman leaves a phone message for her grandfather. He promised he'd protect her, but now she's disappeared.

A little girl, only three years old, is found half-dead on a deserted mountainside. No one has reported her missing. Someone left her there to die.

The two cases seem unconnected, but Dr Clare Hart can see a terrifying pattern emerging. Can she find Rosa? Or is it already too late?
