Sarah is smart, despite her looks. She was born with a disfigured face. So disfigured that it didn't even look like a face. Surgery made it look more like a face, but it doesn't matter. She sees no one but her close friends. Why? Because she's in the care of the FBI. Her parents died when she was young, both the expense of European terrorists. The same terrorists she's working against.
She has also developed a foolproof lie detector test: brain scanning, which the FBI wants her to test on certain subjects.
But back on the side of reality, her aunt, her only surviving relative, is trying to once and for all find her. When she finally does, she discovers that Sarah has no personality because her only connection to the outside world is her movie collection. Hunt has figured out a way for Sarah to not be a real character because of this, and I applaud her for it.
But none of the facts above compare to the originality of the end. Once again, Hunt has gone the extra mile and figured out a creative solution to the worn-out hostage situation plot device.
Besides that, the romantic subplot is introduced in the epilogue. There is also one character in particular who is not as he seems. Truly.
Basically, this book is one of the best of 2008.
