Hello everyone, I am looking to try my hand at a cryptic zone in my sump, I have seen plenty of posts here about Steven tyree and his CMAT ebooks, so much so that I would like to buy it and read for myself. However it appears that his website hasn't been updated in a while and the link to purchase his book no long works. Does anyone know if I can find it anywhere else or of any similar information I can read on the subject
