My next book is called Gospel Deeps: Reveling in the Excellencies of Jesus. At this moment, Amazon is offering it for preorder at $7.91. That's 51% off the cover price. I have no idea how long that price will last, but if you're so inclined to purchase it, this might be a good time to do so.
Thanks for forgiving this shameless self-promotion. I do try to keep such things to a minimum on the blog.
