You may try Pierce's "Basic Category Theory for Computer Scientists" or Awodey's "Category Theory", whose style is rather introductory. Both of them (I think) have a chapter about functors where they explain the Hom functor and related topics.
I think Awodey's book is pretty fantastic, actually, but I'd avoid Pierce. Unlike "Types and Programming Languages", I think "Basic Category Theory..." is a bit eccentric in its presentation and doesn't help the reader build intuition.
