This product misrepresents itself as Starfinder compatible. It's basically a Pathfinder and 5e supplement, with a quarter of one page or so for determining starting HP for hybrid races in Starfinder. If this book can be labled Starfinder Compatible, ANYTHING for Pathfinder is just as compatible. So, if you're looking for Starfinder content, this book isn't worth your time.
