It's Books and Culture: A Christian Review.
I subscribed to it a few months back, and each time it comes in, I indulge myself in its oversize pages, salivating at all the great books I will never have time to read. The book advertisements are so substantial that they're almost as good as the essay-length reviews. Check out the online version, but don't be fooled. It's much more fun for book-lovers to experience the review in its 11-by-17, full-color, papery glory.
Most of the reviewed works are non-fiction. The reviewers are thoughtful, objective, and not mounted on any political hobbyhorses. Essayists also write on cultural issues. This month's review contains a piece examining the prosperity gospel, an analysis of the Cannes Film Festival, and a lament on the decline of the Indiana Jones franchise.
Some sample titles I found in both ads and reviews:
