The evil Shadow Lord has been banished, but famine still stalks Deltora, and only monsters thrive. As the starving people weaken, Lief, Jasmine and Barda discover a terrible secret. The Enemy left the seeds of death behind him. Four vile creations of sorcery called the Four Sisters are hidden in the land. They are slowly killing it while the Shadow Lord gloats, awaiting his triumphant return. The companions must find the deadly Sisters and destroy them. Their only clue is a fragment of an ancient map. Their only hope of help lies with 7 unlikely allies - the last of Deltora's dragons. Everybody in Deltora thinks the dragons have disappeared. But the young king Lief knows this isn't true-and that the time has come to find them. The evil Shadow Lord has poisoned the land with four vile creations of sorcery buried with such stealth that only the bravest of heroes will find them. Lief and his companions Barda and Jasmine must struggle to reveal the origins of the sorcery and destroy them. Their only clue is a fragment of an ancient map. And their only hope of help lies with seven unlikely allies-the last of Deltora's dragons.
