The Washington Post has called Gene Wolfe "the finest writer the science fiction world has yet produced."

This volume, Castle of Days, joins together two of his rarest and most sought after works--Gene Wolfe's Book of Days and The Castle of the Otter--and add thirty-nine short essays collected here for the first time, to fashion a rich and engrossing architecture of wonder.
