The Bard. Tor's Quest, #3

Abandoning the quest is no longer an option The king is dead and his sons must complete a quest in order to take over the throne. What started off as an adventure has become a nightmare. Prince Tor has witnessed the deaths of friends and brothers and has discovered that the quest is designed to kill all who take part. When a clue required Tor and his companions to find 'a guide from another world', a witch dragged a young woman from her own world to a land filled with magic, mythical creatures and dangerous monsters.
She risked her life and went through agony in order to obtain the latest clue; now she must make an even bigger sacrifice. The group has to find the mysterious Bard and convince him to help them, but not everyone they meet can be trusted, as one of them discovers when she pays the ultimate price for having faith in the wrong person. The surprising truth about one of them is revealed and another's true past is discovered.
When Tor is forced to visit a place no man wishes to go, he uncovers the reality of the nightly rituals that take place there. New allies will join them while others are left behind as the quest makes them revisit familiar places, with deadly consequences. They meet old friends once more, as well as old enemies, and discover that the dangers they must face are far from over.
