This book is not a continuation of the Heechee saga. However, it does provide a wealth of background material. Much of the book will already be familiar to readers of the Saga. Two bonuses are noteworthy. There is a long short story (around 100 pages) detailing the life of Audie Walthers when he was an airbody pilot on Venus. This story is pretty engrossing, and gives further insight into the goings on on Venus in the world of Gateway. Also, for those curious after reading Gateway as to the adventures of the other prospectors, there is a section that deals with the successes and disasters encountered by these people. If you are a [big] fan of Gateway, this book should be obtained. Otherwise, the short story about Audie and some additional background material might still convince you to get the book.
