This story is told by a young girl named Annie.
Annie is homeschooled, but she gets a day off when her parents and grandparents throw her a surprise birthday party. Then her grandmother is put in jail for a very silly crime.
Annie comes to her grandmother's aid as an acting judge. Annie and Ike, the toad who is her best friend and guardian angel, try to get Grandmother out of jail. Grandfather arrives just in the nick of time to help.
After the rescue, they avoid further legal problems by escaping to the Moon. Annie's father had been working on a very special project for a long time. It turns out that this project was a colony on the Moon.
Annie meets some old friends in the Moon colony and makes some new ones. Her main companions are Ike, Tina and Tom Turkey, and Mister Archer, the lawyer who had Grandmother put in jail.
There are several pitfalls along the way. Then the day before Christmas, Annie ends up as a driver in the first NASCAR race on the Moon.
Annie has three days of adventures with a very special fourth day, Christmas. The adventure ends with a truly wonderful Christmas event.
