Comparative religion textbooks from a Catholic viewpoint

Most Catholic text books about religion are about Catholicism, I asked my high-school aged daughter what she wants to study next year for religion class and she said she's like to know about other religions. I'm having a hard time finding these kinds of books. Most popular authors will write a book condemning this or that other religion, but I just want one that honestly compares them all without being wishywashy about which is better. Otherwise, I think I'd have to piece together about a hundred books.
