I will put some recommended reading on John Calvin up tomorrow on the anniversary of his birth but here is some other book news that's out there. First, Monergism books is offering free shipping for the month of July (in honor of Calvin's birth). You can get all the details here. Lot's of good books are available there at fair prices so check it out.
Second, Reformation Heritage Books is offering The Hope Fulfilled: Essays in Honor of O. Palmer Robertson on sale for 40% off (just $18). There are some helpful essays in this book and it's worth that price.
Finally, a new book will be coming out from American Vision Publishers in July that looks fantastic. Edited by Joel McDurmon, Presuppositional Apologetics: Stated and Defended by Greg Bahnsen will soon be available. Bahnsen is best known for his "Great Debate" with Dr. Gordon Stein over the existence of God. I think that we can hold that he was one of the greatest apologists in church history and was also gifted in distilling apologetic method in a way that it is understandable. At just a little over 300 pages this ought to be a gold-mine for studying apologetics.
