Let me tell you up front, that I'm not a huge fan of Christian fiction. I do not want to be preached at or given any token Christianity. I read sci-fi, fantasy, paranormals, romance...
Having said that, Kendig does a fantastic job of pulling you into the story and showing you how the characters have God in their lives day in and day out---not just when they're in danger, sick, etc. Nothing in the book feels like token Christianity or a sermon. I esp. loved how she showed how God worked in Reese's life. I think as a society we tend to think of military men as non-religious, but she does an amazing job of showing how God is the only reason Reese can do what he does...including killing and all the other baggage that goes with being special ops/spy-type.
Second, she has a knack for creating characters that embed themselves in your heart. You can't help worrying about them, thinking about them like they're real people....you can't, in fact, help from feeling like they ARE real people.
Overall, I stayed up waaaay too late finishing this book. A great read. One I plan to recommend to all and sundry. Looking forward to her future books!!!
