Solitude: A philosophical encounter by Philip Koch. Honestly, too many examples and references. The schoolteacher in him really, really shows. I'm hooked! Stop quoting people, it's distracting as hell!
A philosophy of solitude by John Cowper Powys.
Yes, there is a theme here.

If you're into the whole psychology thing, I'd suggest the 48 Laws of Power by Robert Greene. Really good book, and it offers an interesting perception on human nature. I only read the smaller shortened edition.
