Happy New Year to you too @Kurisu!
This is a bit old now but still worth a look: https://astonj.com/best-way-to-learn-ruby-rails
And as far as what’s the equivalent to Programming Phoenix… it is https://devtalk.com/books/agile-web-development-with-rails-6 
Rails should feel relatively familiar to you if you know Rails, and I’m sure you’ll enjoy learning it! If you don’t already know Ruby, I recommend learning that first (see my blog post for recommendations) as it will make things a lot easier for you and Ruby is just so easy to learn anyway.
Keep us posted on how you get on - perhaps via a #community:journals
