Query: A good, yet sad, read.

This is a very popular book, but it has a sad story. I felt badly for Kathryn and Mattie, who thought they had a normal happy family, but really didn't. I also thought that the IRA stuff was a little far-fetched, as well as the fact that Jack was able to pull off having (at least) two families. However, I thought that the book was well-written and kept the reader interested.
