Shadowgate — Emily Rodda

An ancient curse.
Seven mysterious dragons.
A race against time.

The Shadow Lord may be gone from the land of Deltora, but he has not been forgotten. His evil remains in the form of the Four Sisters and a number of devious spies who will stop at nothing to return the Shadow Lord to power.

Lief, Barda, and Jasmine have found and destroyed the first of the Sisters. Now they must find the second, hidden within the treacherous mountains that border the Shadowlands. There they discover masked tricksters, vile wanderers, and artful thieves -- all with their own secrets and plans. It will take cunning, strength, and the help of dragons for the three heroes to make it to Shadowgate and defeat the Sister of the North's terrible, mysterious guardian.
