Reylie and Ron King are suddenly transported into a Wild West alternate universe through a game created by their grandfather. They land right in the middle of a group of outlaws led by the tough Bar and his Uncle Jake. The outlaws' plans go haywire with the siblings' unexpected arrival, throwing them into a whirlwind of danger and adventure.
The earth is in chaos due to natural disasters, but the Sky Tunnel technology developed from the game offers a glimmer of hope for humanity's survival. As the siblings' adventures unfold, more people-scientists, Marines, and even their Aunt Jasmine!-are pulled into other alternate universes. The journey is filled with danger, excitement, the quest to unlock the secrets of the Sky Tunnels... and the game that started it all.
