Stephen Reeder Donaldson (born May 13, 1947) is an American fantasy, science fiction, and mystery novelist, most famous for The Chronicles of Thomas Covenant, his ten-novel fantasy series. His work is characterized by psychological complexity, conceptual abstractness, moral bleakness, and the use of an arcane vocabulary, and has attracted critical praise for its "imagination, vivid characterizations, and fast pace". Like that of many of his peers, his writing is heavily influenced by the works of J. R. R. Tolkien. However, Donaldson's stories show a wide range of other influences, including Mervyn Peake, C. S. Lewis, Robert E. Howard and the operas of Richard Wagner. Less
