One Amazing Trip To Garzon

Two kids go into the woods where they replace a mysterious portal that leads them to another planet. When the portal closes will they replace a way home, or be stuck on a planet millions of miles away? In what was once an ordinary rural town in the middle of Illinois for two young kids has turned into something much larger when they replace something strange in their backyard. When they are transported to another planet and have no way of making contact back home, will they persevere and replace a way back to their home with their family or be stuck forever?
