As for a recommendation, I loved all of them, but it comes down to what you want.
If you are just starting out I would recommend Unmarketing, as it is easy to read, has some great stuff in it and is even funny. 
If you want to know more about how to create and use content then definitely Content Rules. That book has helped me a lot.
@joanmuschampfagnani I haven’t read Enchantment yet. I should give it a read.
Cheers!
