Perfect Match

I read Perfect Match. by Jodi Picoult.
its about a young boy whos sexually abused by a priest. What happens is that everyone falsely accuses a priest of doing it, when it was actually a visiting priest. The real molester had a bone marrow transplant from the falsely accused priests, show they shared DNA.
The mother of the boy, who's a DA, actually ended up killing the falsely accused priest. The jury couldnt reach a verdict so she wasnt charged with murder, just manslaughter, but her sentence was suspended.
