This book is all about mass disappearances which have occurred in history.

These events run the gamut from entire villages whose inhabitants disappeared to a flight of military planes gone missing in the Bermuda Triangle.

Many ships have disappeared so I only cover a few of the most notorious ones.

I also do not usually cover missing families or where just several people have gone absent.

It is much more interesting to me if an entire army became lost and missing or strange things happened to a group which has become a big mystery.

There are also some recent missing persons mysteries since these events happen even in the modern age.
