I'm not the author of the book, but I bought and enjoyed it quite a bit. https://pragprog.com/titles/sbelixir/from-ruby-to-elixir/ https://pragprog.com/titles/sbelixir/from-ruby-to-elixir/ From Ruby to Elixir, by Stephen Bussey. He's also written a book named Real-time Phoenix which I also found pretty helpful.
