One the same subject and as accessible, I love the two books from Jay Cummings: Proofs and Real Analysis. Each just $16 on Amazon. It is a joy to read these books and try some of the exercises. I wish PDF versions were also available... For those interested: https://webpages.csus.edu/jay.cummings/Books.html https://webpages.csus.edu/jay.cummings/Books.html
