A girl splashing in waist- deep waves is attacked by an 8- foot tiger shark. A teenager has to 'tightrope walk' on an icy steel beam 40 feet above hard- packed snow to save a little girl dangling from a ski- chair lift. An eight- year- old drives her injured father's half- ton truck miles over treacherous roads to get help for him. These are some of the most exciting and suspenseful stories ever written, and they're all true!
