Why, as a matter of fact, it is a book contract. I'll announce more details shortly, but you should be preparing yourself for another spiritual book no later than the summer of 2014. And ANOTHER ONE in the summer of 2015. Make some room on your bookshelf. Or in your digital library.
As you can see, these two books will be coming to you from Baker Books. I'm excited to be working with the folks at Baker... they seem intelligent, fun and are trying new and interesting things.
