Thr3E by Ted Dekker (2006, Paperback)

Ted Dekker is known for strange stories and eccentric characters, but when I started reading this I was lulled in to a feeling of peace. The suspense starts right away, but you have to read about half the book before Dekker pulls his usual 'knock-you-off-your-feet' routine.
The story was well written (read it a second time and you'll be amazed at how Dekker pulled this off; I won't explain that statement because it would ruin the ending for you, but trust me, Dekker is amazing) the characters were people for whom you felt immediate emotion, both positive and negative, and Dekker keeps you guessing until the very end. He even tells you things about the ending without really telling you and you won't believe the ending anyway.
Absolutely wonderful book. Kudos to Dekker for another great novel.
Some people knock the book because of loopholes or inconsistencies. I disagree. The book flows well and the ending is both possible and believable.
Without giving away the ending, I will say that the book is possible, the ending is possible and the reason is simple. People have serious issues. Why do you think the church, psychologists, psychiatrists and therapists are so profitable. Because people have problems, some more than others, and people react differently to the problems. Also, there are mental wards for a reason.
FYI, an independent film company made the film recently.
