The Portal: The Cort Chronicles Book 1

After falling into a time portal during a Little League baseball game in Trinity, New York, eleven-year-old Andy finds himself transported to a ghostly version of his hometown-101 years in the future. Twisted metal, rotten wood, and garbage litter the seemingly empty streets, but Andy will soon discover that the city is controlled by CORT robots . . . and that this reality is Earth's possible future. When thirteen-year-old Zack receives a strange letter that guides him through the portal, he and his brother are reunited, and together they must journey through a nightmare world that only they can change. But how can two young boys alter the present by saving the future?
