The Last Peanut Butter and Jelly Sandwich

Darwin L. Clarence III, called Dancey since he was in nursery school, has eaten his favorite sandwich for lunch every day for years - peanut butter and jelly.  But his parents are moving to another planet, one where they don't grow peanuts or strawberries.  These are Dancey's favorites. Leaving them behind is not something he can live with.  So Dancey has a plan.  However, he has no idea of its far-reaching effects or how much it will change his new world.
