Well written, but not much Christian fiction to it, and what little there was from a Catholic viewpoint.
If you want a mostly secular spy thriller, this would be good.
I look for scripture, doctrine, and application of scripture, in Christian fiction, otherwise, I would read just secular novels. God was slightly mention, Jesus not at all and so on.
Still it was well written, but I will not be reading this author again, because I prefer true Christian fiction.
