The Bride Collector

I got a free advance copy of The Bride Collector in return for blogging about it. :D So here I go.

What is love? What is free will? What does it mean to be the bride of God?
The Bride Collector, so named by the FBI who are tracking him down, has taken it upon himself to take seven of the most beautiful women and present them to God, as His bride - by killing them. He tells himself he is God's messenger.
On a hunch, Brad Raines, FBI agent, turns to an unusual source: a local center for the mentally ill called the Center for Wellbeing and Intelligence, which houses those with mental problems but who are also quite gifted in one or several areas. While there, he meets a young woman named Paradise, a girl diagnosed as schizophrenic who can see ghosts and feel the last few moments of someone's life if touching their dead body.
While trying to work on the case, Brad finds himself confronted with difficult questions about love and sanity. Could it be that the people called "different" by society and made outcasts are truly those most in touch with reality?
Ted Dekker, as usual, wrote a twisting, thrilling book that I stayed up late into the night reading. I couldn't put it down! It broaches difficult questions and proposes deep thoughts, and even after the final page a person is left chewing on the content in their mind and trying to decipher it.
There is some content that, were it a movie, would rate it PG-13, in my opinion. A girl has flashbacks to nearly being raped, people are killed, etc. But nothing disturbing, and nothing that makes it any less an amazing, gripping book.
I would recommend this to anyone who's old enough to deal with the stuff I just mentioned. I'm fifteen, and I loved it. How Ted keeps managing to come up with this stuff is beyond me!

What does it mean to love? What does it mean to be loved? What would drive someone to kill to please God?
Who is the Bride Collector?
