Green

Ted Dekker's Green is part of his Circle Series and he notes that this book can be read first or last as part of that circle. Since I read it last, I had to skim back over Black, Red, and White to understand the circle theory and place Green into the circle's sequence.

Thomas Hunter, the main character, continues to travel between the past and the future with dire consequences to both worlds. In the histories, the fall of mankind keeps good and evil in the spiritual realm. But, in the future world, good and evil can be seen, touched and tasted until mankind once again rejects that reality creating apocalyptic results.

The circle's story continues with the The Books of History Chronicles broken down into two additional series: The Lost Books (Chosen, Infidel, Renegade, Chaos) and The Paradise Novels (Showdown, Saint, Sinner).
