#37 Heat Wave #38 The Perils of Love With over 11 million copies sold in the series, Left Behind: The Kids is a favorite of readers ages 10-14. Each book follows a group of teens who were "left behind" when other friends and family members were taken to heaven by God in the Rapture. All they have left is their friendship and their growing faith in Jesus Christ. For them, the last several years have not been easy . . . but the end is near. With background plots from Left Behind #10: The Remnant and #11: Armageddon, these books will thrill even reluctant readers with cliffhangers from book to book.
