This is a charming story of a father and son who are home sitting on the couch, when the son decided that the couch is  a big boat and they are actually floating in the ocean.  The father plays along with the imagination game and soon they are running from sharks, fishing for food, and paddling to a life saving island.  They build a fort, as shelter and create a fire to lay next to as they star gaze into the night sky.  It ends with the son telling the father, “You’re the best.  For pretend and for real.” Nice Water color and pen/ink illustrations.  Recommended.
