Can you recommend good books on philosophy?

I am interested in reading some good books that focus on philosophy and its relation to Catholic theology. Can anyone recommend some good books with which I can begin my foray into philosophy? Any recommendations that can get me started would be greatly appreciated.

You might start with Peter Kreeft and then read those writers he discusses.
