Even coming in with a few years experience in Clojure and having spent time writing macros in Elixir I have found this to be a really worthwhile read (so far).

That said, this should not be your first Elixir book (as Chris points out in the book's introduction). It should be your second, especially if you are interested in writing libraries.

Dave Thomas' Programming Elixir should be the first :)

Agreed - fantastic book and very well written.

You can get a taster of it by watching his keynote at ElixirConf. [1]
