Just Grace gets invited to Grace F’s sleepover birthday party, which will be outdoors with sleeping bags and tents in her backyard.  Grace worries about bugs, bears, and mean older sisters.  Forgetting to make Grace F. a birthday card, Just Grace invents a ghost inside a recycling bin to deflect attention.  The small lie snowballs and soon the whole school begins lining up to “see” the ghost.  Grace doesn’t know how to let people know there is no ghost without admitting she made it up.  Just Grace has a practice sleepover with her dad in their own backyard and realizes there is nothing to worry about.  She also finds a way to solve the ghost problem.  Just Grace books are told in the first person narrative.  The books are filled with list and drawings to explain and illustrate Grace’s view of things.
