One of the King's knights has gone missing. Sent to explore the mysterious Wild Wood, which no-one dares visit and some say is enchanted, he has vanished in the snow. Tiuri - now Sir Tiuri after carrying out his last perilous mission - has to find him. With his best friend and squire, Piak, he must journey into the heart of a terrifying, secret forest realm, where danger is all around and every path leads you astray. It is a place of lost, overgrown cities and ancient curses; of robbers, princesses and strange Men in Green; of old friends and treacherous new enemies and a secret plot that threatens to bring down the entire kingdom.
