I really enjoyed the previous novels in this series. Jack makes the future believable. In this story our heroine "Hutch" returns to space to track down the "Moonriders", alien ships that are make a nusicance of themselves.

Enjoyable. Saw the climax a mile off but the story held and McDevitts narative swept me along. Some online reviews were negative about this book when compared to others in the series, but I liked it and thought it an appropirate finale to the "Hutch" storyline.
