So that's... a little broad. You mean a book on the history of Catholicism? Nothing comes to mind, but let me think about it. (And ask my mother. Hey mum, what should she read?)
If you've never read Huston Smith's The World's Religions, that might be a good general religion book to start with. Although, if your upbringing was anything like my Unitarian nieces', world religions would probably not be the hole in your religious education. :-)
I'm more used to suggesting books on progressive Christianity to non-progressive Christians, but that's a totally different reading list (mostly consisting of lots of Marcus Borg, including The Meaning of Jesus: Two Visions, which he co-wrote with conservative scholar NT Wright; and Remedial Christianity, which despite a condescending name and a dismissive attitude towards conservatism is good and, more importantly, fun to read).
