The Last Dark: The climax of the entire Thomas Covenant Chronicles (Last Chronicles of Thomas Cove)

“It will take a long time for fans or critics to digest and appreciate Donaldson's almost 40-year achievement. But in time “T he Chronicles of Thomas Covenant” will be seen as one of the self-defining works of the third millennium, our equivalent in scope and ambition of earlier epics and fantasies, from Virgil's “Aeneid” to Tennyson's “Arthurian Idylls” and Tolkien's “Lord of the Rings,” the last now a lifetime (Donaldson's own) in the past.” -The Wall Street Journal

Compelled step by step to actions whose consequences they could neither see nor prevent, Thomas Covenant and Linden Avery have fought for what they love in the magical reality known only as "the Land." Now they face their final crisis.  Reunited after their separate struggles, they discover in each other their true power--and yet they cannot imagine how to stop the Worm of the World’s End from unmaking Time.  Nevertheless they must resist the ruin of all things, giving their last strength in the service of the world's continuance.
