I'm not sure if this question has been asked before. I'm interested in finding textbooks that are "like" Stephen Abbott's Understanding Analysis. The distinctive feature about this textbook is that it motivates the reasoning involved in the proofs prior to presenting the proofs, making the construction behind the proofs seem all the more reasonable.
I'm hoping if other people can list textbooks similar to Abbott's book in other fields of study, algebra, complex analysis etc. The books need not be at a level comparable to that of Abbott's books; the books can be of intermediate-advanced difficulty as well.
