There’s the link to An Evangelical Mess: Essays on American Evangelical Culture from an Evangelical’s Perspective. It’s available cheap.
I’m already in the works for my second (and third, actually) ebooks. You can get the first part of my next one by subscribing to my email list (the pop up or the sidebar on the right-hand side). If you sign up for the email list, you’ll know ahead of time exactly when my next ebook will come out.
No worries if you don’t have a Kindle. You can download the app for free on your phone or tablet.
