Hello SEOmoz,
First question here on the forum, but a silent follower for years 
I'm looking for a good book - you define what is "good" - about content marketing and or persona creation that you read and proved to be usable in real-life situations
I've read "Accelerate" but found it too light-weight.
Therefore your recommendations would come very in handy.
Looking forward to your replies!
Best regards,
Nikolaas
