"I "I have to confess, right up front here, that you will not find a great deal in the way of poetic vision in these stories, or singing prose, or deep insight into character. Nor are these stories that will tell you much that is new to you about the human condition. These are stories in what is now pretty much a lost tradition in science fiction, the simple and unselfconsciously fast-paced adventure story of the pulp-magazine era. They are stories from the dawn of my career, which began in the closing years of that era, and are straightforward tales of action, in the main, that were written partly for fun and partly for money." -Robert Silverberg, from the Introduction
