I have an Easter sale going! First off, a bundle of all of my books, including the ones no longer available for sale elsewhere. It's more than 60% off the full price

But the interesting part of this is an experiment where, included in the bundle, is a preview of the book I'm working on. Buying the bundle, or the preview separately, lets you join a newsletter where I'll be documenting my progress on the book.
