Circle Series 4-in-1 by Ted Dekker
My rating: 5 of 5 stars
Very good realization and imagery, bringing spiritual struggles into stark physical reality. Extremely creative and colorful writing. The books were written in a cyclical path, this particular collection starts with Black, but contains an alternate ending to Green if you wanted to start there. Overall, the series started off slowly, but the intensity ramps up continually until the ending/beginning. Overall, a great read, and a great twist on a timeless tale of redemption.
