I am going to try and order the books in terms of complexity too.
My current thinking is:
Programming Elixir
Introducing Elixir (perhaps as an optional bonus - as I am guessing this is aimed more at those coming from Erlang)
Elixir in Action
The Little Elixir and OTP Guidebook
Metaprogramming Elixir
Programming Phoenix
Or maybe reverse the last two. What do you think?
