Ace D-391 Siege of The Unseen - AE Van Vogt

Ace D-391 pairs A.E. Van Vogt's "Siege of the Unseen" with John Brunner's "The World Swappers" in classic double novel format. This 1959 first printing shows the typical wear you'd expect from a 65-year-old paperback, but remains complete and readable. Van Vogt's mind-bending science fiction gets the full Ace treatment with that iconic cover art and compact storytelling. The scans show the actual book condition - honest wear that tells the story of decades on shelves and in hands of sci-fi fans.
