Lee has promised seven books, there are already several available. The second in the series, Outlaw Trigger touches on the quality of faith in God, and how Scott handles adversity. Any faithful person can see themselves in Scott. Especially those of us who have allowed that adversity to destroy or at least change the depth of how we believe. Most of us would think we could not recover from this kind of loss. Scott believes that also. In addition, he becomes more skilled at killing aliens. Several kinds of aliens. Why are they here anyway? They don't ever follow through. They fall back just when it seems that they have conquered the humans. The sequels are there, available through book 4 already. I now own all available, and can't wait to start the 4th book. Unfortunately, life also happens. I can't give up everything, but I can skip some sleep over the next few days. I probably will. Lee, with this book and Hero, I have given up many hours of sleep. I will again. I love the characters. Thanks for catching my attention.
