A book to help you choose your POV. Whose story are you really telling? And what POV would be best for it? Plus examples (same bits of stories told from different POVs), rules, conventions, pitfalls and advantages of one or the other POV. Also, if you want to learn what melodramatic writing is and how to avoid it (my case), these are a few excellent examples here that will make you "get" it (I certainly "got" it).
