Good book for razz

Hi guys, I'm a razz poker player and have been doing fairly well in razz, but I wanted to learn a bit more theory on the subject. Does anyone here know any good razz books? Hopefully modern? Or if you know any youtube channel/ forum or whatever place on the internet that discusses razz a lot let me know!

Not sure about this one, but its the most recent:

Razz kinda fascinates me, worst hand wins!
