A list of works in philosophy for summer reading, please?

[The One and Only...]

I'm interested in reading some philosophical works over the summer. Not broad, summarizing textbooks like I already have; actual works, such as those by Plato, Hume, Kant, Nietzche... the list goes on.

I'd like to read works on as many different branches of philosophy as possible. The idea is to gain a more thorough understanding of various positions in philosophy that have evolved through the ages. I'll need to read classics, of course, but modern (and postmodern) pieces should not be ignored.

Can anyone recommend a list of books to get started?
