Good book about Akka library and actor-based concurrency model [closed]

Question

I am looking for a book which cover Akka in detail. Specifically the book should cover best practices in actor-based concurrency, what pitfalls should be aware of? I actually tried searching for a while but could not find even a book about Akka.

Answer 1

Already plowed through the 330 pages of Akka Documentation?

Answer 2

How about Akka in Action? Once it is out of MEAP of course.
