I received a review copy of this book, but no other compensation.

This book comes with a lot of content, and new archetypes for non kineticist, but the really cool part was the new mind element. It's more than twice the size of any first party elements and has a huge amount of customization. The wild talents alone left me with a ton of character ideas to play around with, and it has a way more occult feel than the base class, which is nice. Overall, I'd say the Mind element was the really big draw here even if everything else was great, just for the variety of abilities it opened up.
