Is there any book similar to "Halmos Naive Set Theory" in Category Theory? When I wanted to learn set theory in high school, I found Halmos Naive Set Theory  book very readable and understandable. But now, at university, I have been searching for a similar book in category theory, but I haven't found any book like that until now.  
What is your suggestion?
Thanks in advance.
