Twirly is a helicopter involved in adventures during normal daily activities. Sam, his pilot, takes him on interesting missions that create adventure and surprise. The book is about heli-skiing and aspects of the unknown situations that can happen unexpectedly. Twirly loves being piloted by Sam, who explains the risks and dangers of scenarios that happen to them. The story begins when Twirly and Sam take four skiers to high mountain peaks to experience heli-skiing, only to have a natural cause create upset and worry. I can see Twirly wiping his brow as the experience becomes more intense and worrisome. My son was a helicopter pilot, flying on different missions, and was able to provide me with a better understanding of the things that have happened in his day of flying.
