Howdy -
Looks like BtDYK is in trouble again at Amazon. They're deciding whether or not to keep carrying it because it goes against their content guidelines. I went through this with Amazon back when I first published in in 2015 and they decided to accept it. Don't know why this has changed, but hopefully I'll get some answers. In the meantime, I've made it available here at payhip at a discount: https://payhip.com/b/S1Zq
(ps… the audiobook is coming… :D )
