As I've been on my rear with a virus (who knew a doctor can't prescribe medication for a virus? huh....anyway) I've had some time to read. So I've read the Ted Dekker trilogy of the Circle.
The first book is Black, the second is Red, and the third is White.

Honestly, if you dig fiction, go the library and get these. They've been out a few years now, and they were amazing! The scene of Eden in the first one brought me to tears in my desire to be home with Jesus. I'm not kidding, and I don't think it was the high fever and Dayquil entirely at fault.

I really encourage anyone who enjoys fiction in the whole espionage, fantasy, spy game genre to check this series out. It's well worth it.
