Query: One of his very best

David Drake writes military science fiction like no one else, and this novel is one of the best examples of why. It has large quantities of intense action, character development under fire, and a mass of memorable characters.In many ways the book is what a Slammers' story would be like if you boiled it down to the essentials and then escalated the action another notch.
