The Adventure of the Denver Walker
by Kevin L. O'Brien
Col. Eile and Maj. Sunny have been given a desperate mission: destroy the alien robotic Walker before it destroys Denver. However, their weapon uses unproven technology, and the Walker's defenses are nearly impenetrable. They know it's a suicide mission, but millions of lives are at stake. They must succeed, somehow, no matter the cost. This is a short story, with a Preface and Sample Excerpts.
