Fatal Revenant - The Last Chronicles of Thomas Covenant, Book 2

Linden Avery, who loved Thomas Covenant and watched him die, has returned to the Land in search of her kidnapped son, Jeremiah. As Fatal Revenant begins, Linden watches from the battlements of Revelstone when the impossible happens- riding ahead of the hordes attacking Revelstone are Jeremiah and Covenant himself, apparently very much alive.
