Fairbanks Daily News Miner “Liefer…cuts right to the meat of a usually murky situation...he has the experience, knowledge and chops not only to examine an aviation crash, but also to speculate about its cause. Readers will enjoy this book…”

Pacific Flyermagazine, www.pacificflyer.com "…factual events of these significant disappearances are presented with meticulous insight.”
Aircraft Wreckswebsite, www.aircraftwrecks.com "Thoroughly enjoyable book that leaves the reader wanting more, well researched and focused on seventeen disappearances. Only two of these cases have been solved to date, and the others tantalize us with a myriad of questions and possibilities."
John Tippets, author of Hearts of Courage "Aviation Mysteries of the North is exceptionally well researched and a reader should appreciate the extensive use of pictures, maps and other illustrations. If you are fascinated with aviation and/or really enjoy Alaska history, you will appreciate reading this new book by Gregory Liefer."
