I´m back here to tell you that my book of idioms is now available in paperback. Now we have the best of both worlds: Kindle and paperback!
You can find it on Amazon US, Amazon UK and Amazon Spain, among others.
I don´t know about you, but I love the feeling of holding a book in my hands and turning the pages the way I´ve done most of my life, haha.
Needless to say, I will keep working on the book for the second edition, which will include lots of illustrations and more idioms, sayings and proverbs.
