The Circle Trilogy includes four books Black, Red, White, and Green. The circle trilogy takes place in two worlds: present time Earth and the other is 2000 years in the future after the world has come to an end. Thomas hunter is the main character in this series. Every time he falls asleep in one world he wakes up in the other. God has sent a new Adam named Tanis on earth. God gave him an advantage by letting him see sin itself hoping that we would not make the same mistake as last time, but as Tanis sets out to kill Teelah which is the devil; only to be manipulated by him into drinking the forbidden water which releases evil across the world.
