As the wind roared, Viktor realize the therapy was never meant to heal Anna. It was his final, dangerous attempt to face the truth—or lose his mind trying to find it.

Die Therapie began not in an office, but in this isolated prison of a cabin. Each session with Anna was a violent excavation of his past. She told him things no one could know—the color of Josy's favorite teddy bear, the strange illness the doctors couldn't diagnose.
