We are moving full steam ahead with this series. We recently finished Tribulation Force (Book 2 of the series) and I've placed a hold for the third book. I wanted to complete the series by Summer and it looks like I'm going to meet that goal.
I'm finding this series well written and suspenseful (even though I'm still on the parts I've done before). It makes me want to catch up and get to the stuff that is new to me. I also must admit even though this is fiction it has given me new things to study in the Bible.
