I have enjoyed this series from the beginning, but the authors are getting ridiculous. It's like Jenkins and LaHaye want to milk their cash cow for all it's worth and don't want it to end. The book should have been titled "The Rescue of Sebastian" because it seems that's all they covered. I'm done waiting for these books, and done reading this series.
