Has anybody heard of the "Left Behind" series of novels?

I'm an avid reader and was looking on the internet for new novels to read and I came across this series called the "Left Behind" series. It deals with the "End Times" of the Bible, a.k.a. The Apocalypse. The thing that struck me about it is that it is written by Christian authors and made for a Christian audience. I am not very religious at all and was wondering what people think of this series. By the way, the Antichrist is from Romania, where I am originally from, so that also struck me as interesting. I guess they were working on the whole Vlad Tepes/Dracula spiel.
