I am not a subscriber to Christian Century, but I do occasionally read it and I have an RSS on their book reviews (most of which are subscriber only.) But today they posted 9 short reviews of a wide range of Christian non-fiction (mostly theology) books.
Everything from Retrieving Nicea: The Development and Meaning of Trinitarian Doctrine to iPod, YouTube, Wii Play: Theological Engagements with Entertainment to studies of Hans Urs von Balthasar and Jonathan Edwards.
