Deltora Quest Series 3 Boxed Set

The evil Shadow Lord has been banished, but still famine 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 seven unlikely allies – the
last of Deltora’s dragons. Deep in the Shadowlands, when the
evil Shadow Lord learns that Lief, Barda and Jasmine are again
on a quest, he plots their destruction. Terrible dangers from the
present and the past lie in wait for them.
