Query: Rescue on the Edge

Spike Walker has a gift of taking the reader off the page and into the frigid, storm-swept Alaskan waters where fishermen -- and sometimes their rescuers -- find themselves, fighting to stay alive. Mr. Walker painstakingly details the accounts of a few choice Alaskan rescues -- and failures, all heroic. The action is gripping and real because the author knows how to tell a story. Coming Back Alive is extremely informative without weighing down the reader with too much technical and superfluous information. There's no guessing about what happened out there in the isolated Alaskan seas because Mr. Walker has followed through with years of research and interviews.
