 RecommendedPros: 

Great primer on growth marketing, accessible to those new to the topic

Cons: 

@seanellis I'd love more content on Growth Equations!

This is a great overview on Growth Hacking, what, why and how to get started at implementing it for your organization.

I recently bought a copy to give to our CTO to help spread the growth hacking gospel internally, and the book is doing a great job of bringing everyone up to speed as it does the rounds internally.
