A nearly wordless book, the story is mostly told through the pictures, but the connecting thread running through the whole book is a single word accompanying each picture, and as the reader proceeds through the story, that single word changes by just a single letter each time (plan, plane, planet, plant…until it circles all the way back to plan again).  The chain of words provides a wonderful way for young students to consider word structure, and how that single letter changes the word, and the illustrations turn this chain of words, that would otherwise be connected by nothing else, into a story of a young girl and her dog on a farm, who find a photo album telling the story of the old bi-plane in the yard, and cook up a plan to resurrect it with her father to bring it back to new adventures.  It even manages poignancy within the simple tale, as the word pain is accompanied by the illustration showing the family laying flowers at mom’s grave in remembrance.
