This is a story of a young boy’s imaginary friends when he was a child. When he is grown, he realizes they are not real and he must let them go free, perhaps to keep another child company. The author’s own daughter had an imaginary mouse called George Mouse which still remains very much in the memories of the family. Children have a wonderful ability to blend real and imaginary, to compensate for loneliness or other grown-up circumstances out of their control. With maturity, other coping skills come into play and the imaginary friends are replaced by real ones. The book is filled with bright, recognizable, colorful illustrations.
