The Lake of Tears (Deltora Quest Series)

Lief, Barda and their unruly new companion, Jasmine, are on a perilous quest to find the seven gems stolen from the magic Belt of Deltora. The golden topaz has already been found. But only when all the gems have been restored to the Belt can their land be freed from the dark power of the evil Shadow Lord. To find the second stone, the three heroes must travel through territory rules by the monster-sorceress Thaegan. Their journey is filled with treachery, trickery and danger, and at its end they must face the hideous guardian of the enchanted Lake of Tears.
