"As Joe and Katie stared into the attic, their mouths gaped open in surprise at what lay inside."

The attic has been closed for the past 12 years. Mr. and Mrs. McClain didn't dare to enter it because of the accident. The attic isn't even known to the kids, until one day, when Joe and Katie hear a mysterious sound coming from the stairs leading to the room. And when they venture inside, they go on the adventure of their lives into the past and to the Garden of Eden.
