In this thrilling time-travel adventure, a teen survives a modern-day disaster only to be chosen to lead a space mission hundreds of years in the future. There’s no disease, crime, or war on twenty-fourth-century Earth, and new technology allows humanity to travel across the universe. But the adults can’t go everywhere. Only the teenagers can teleport across space and time, which becomes a problem when disaster strikes, and those kids need help. Fortunately, Operation Hourglass comes to the rescue. Back in 2021, Olivia Becker has lost everything to a raging wildfire that claimed her home and possessions. Even worse, Olivia’s dad has taken her to live with his fiancée and her kids. Olivia would rather be anywhere else, and thanks to Operation Hourglass, now’s her chance. She is chosen to lead a team of other time-yanked teens from across history on an interstellar rescue mission. There is Najwa, a nineteenth-century Javanese girl; Leonidas, an athlete from ancient Greece; and Everet, a twenty-fourth-century pilot. Together with the floating AI named Giotto, they jump to the beautiful planet Noros, where furious storms threaten three hundred stranded teens before time runs out . . .
