Left Behind: The Kids #26-28, by Tim LaHaye, Jerry B Jenkins, & Chris Fabry. Paperbacks.
I grab these books from the library in batches, 2 to 3 at a time, a few times a year. The completist in me needs to finish this series (40 books total), which meands I will have read the entire Left Behind oeuvre. A cultural phenomenon for a time, reflective of evangelical culture of the 1990's, the series was originally intended to be a trilogy, then a seven-book series, and ended as a 12-book series with a trilogy of prequels and a final sequel. And these 40 young adult books. And I am so close to wrapping it all up.
