Hi,
Hope you are well. I am trying to get back to reading fiction. So my recommendation is:
If you have not watched the movies, the Godfather is a brilliant book to read. Its got mystery, character development, and a brilliant plot line. If you have watched the movies but want a book which such vivid descriptions that it rekindles your ability to dream and imagine, then this is a great start.
Looking forward to writing to you with more recommendations.
