The Valley of the Lost

The Valley of the Lost is the seventh book in the Deltora Quest novel series written by Emily Rodda. The final gem from the Belt of Deltora is in the mysterious Valley of the Lost with its guardian only known as the Guardian. To retrieve the gem, Lief, Barda, and Jasmine must play his game. If they win, they get the gem. If they lose they will stay trapped inside the Valley of the Lost forever.

After having reached the Maze of the Beast and finding the amethyst, they continue their journey off to the Valley of the Lost to retrieve the seventh and final gem, the diamond. The seven gems are the lost gems from the Belt of Deltora, which had been stolen by the Shadow Lord to overthrow Lief's country, Deltora. The three travel along the river Tor, passing villages that have been raided by pirates. When they stop for a rest, they see a pirate ship. Realizing that it was the ship that a boy named Dain was captured aboard upon, they steal a rowboat in an attempt to rescue him. After Dain and a polypan climb into their boat, the polypan rows against the flooding currents of the river away from the pirates and toward shore. The polypan jumps out of the boat before the boat reaches the shore, and Lief, Barda, Jasmine, and Dain are floating adrift the violently overflowing river. They drift over a sand bar and arrive at the edges of Tora, a great city that Dain had been trying to travel to. They enter the city, and Dain is significantly weakened by the magic of the purifying entrance. They meet two Resistance members, Doom and Neridah after finding the city deserted. Neridah travels with the trio to the Valley of the Lost to find the seventh gem. Upon entering the valley, they meet the Guardian, who doesn't use physical force, but games to protect the diamond. The Guardian enchants them to enter his castle, and asks them to play a game with him for the diamond. The winner of the game will keep the diamond, but the loser will have to be kept in the valley forever. Scared by this, Neridah runs away, leaving the three behind to play the game. Lief, Barda, and Jasmine manage to find all of the clues and guess the name before the time is up, and realize that the Guardian’s name is Endon, the king of Deltora. They also find out that Doom had been there before and won the game, but did not take the gem because of his shock when he realized that the Guardian was actually the king. Lief, Jasmine, and Barda find out the gem is not the real diamond, and leave the castle to find Neridah had stolen it. The diamond curses those who gain the gem by theft, and Neridah dies by tripping on a rock and drowning in a stream. After the trio retrieves the gem, the Valley of the Lost disappears and all of the creatures in it are replaced by people, who reveal themselves to be the people of Tora. They had been turned into their form because they broke a vow that they had sealed by magic by turning King Endon away when he sought refuge with them, as they had no wish to draw the Shadow Lord's forces to them but did not consider the consequences of this action. The Guardian turns into Fardeep, a mere man from Rithmere, but not Endon. The name Endon was actually the Shadow Lord’s idea, and was intended to trick any winners of the game. Knowing that they have all seven gems, the three travel with Dain back to Del to find the king who will put on the Belt to banish the Shadow Lord from Deltora.
