Based on the best-selling Left Behind series for adults, this youth fiction book tells the story of four teens (Judd, Vicki, Lionel, & Ryan) in the suburb of Mount Prospect, Illinois. They are connected in ways they won't begin to understand until later in the series, but for this book they are all greatly impacted by the disappearances of millions around the globe. They soon find out their loved ones have been "raptured" - as believers in Jesus, they were taken to heaven in a flash. Judd, Vicki, and Lionel's families are all gone, as they were the only ones who chose a different path; Ryan's parents die as a result of the disappearances, and he is actually orphaned.
This is a strong beginning to the "Young Trib Force" books and I can easily recommend it for your pre-teens and teens.
