Amazon.com has a book by a renowned scholar, some other guy that I just happened to come across, and Hugh Ross.
Pope Benedict XVI
The Fathers of the Church: From Clement of Rome to Augustine of Hippo for $1.99.
Sidney Greidanus -
Preaching Christ from the Old Testament: A Contemporary Hermeneutical Method for $3.99.
Hugh Ross -
More Than a Theory (Reasons to Believe): Revealing a Testable Model for Creation for $0.99.
Darwin's Doubt (mentioned above) is still $1.99. Maybe the super-secret source knows the score.
