THE TWISTY NEW THRILLER FROM THE NO.1 SUNDAY TIMES BESTSELLING AUTHOR OF THE SANATORIUM AND THE RETREAT

If you lose yourself in nature
Make sure you can find your way back...

Kier Templer lives her life on the road. Dubbed 'the monster's daughter' after her mother's infamous crime, she's left her hometown and twin behind. One thing still ties her to her brother - the maps she creates and sends him of the places she's been.

But then she vanishes from the Portuguese national park, with no map and no trace.

Detective Elin Warner arrives in the park ready to go off-grid and forget the stalker who has been shadowing her steps. When she discovers Kier's final, disturbing map, Elin can tell Kier didn't vanish by choice, but in the wilderness she has to tread carefully. The few strangers on the lonely campsite seem to close ranks against her questions.

Elin must untangle the clues Kier left to find out what really happened.

But when you follow a trail, you have to be careful to watch your own back...
