Witty and Thought Provoking . The Duet was a fun book to read. It included the kind of writing I enjoy; real and coversational. All through the book, I felt like I had known these people for years and were talking to them in my own living room. It was great reading and I would recommend it to anyone needing a light novel
Output:
POS
