This book identifies the letters D and R,

as well as sight words up , down , left and right .
The setting is on Metaphor Mountain and there are metaphors
highlighted in color and used within the story.
The daring letter D finds himself in a jam as he is stuck
hanging from a tree by his backpack while hiking.
As he is swinging left and right he ponders his situation.
Much to his relief, the reliable letter R arrives on the scene and uses
a clever, yet simple, idea to save the day.
