Tuned In - great book, describes how to really understand user perspectives as opposed to 'inside-out' development. The book's based on many principles taught in the Pragmatic Marketing prodm course.

Inspired (Marty Cagan) - good cross section of PM, covers People, Process and Product separately. Startups to large companies.

The Art of Product Management - a series of articles, describes software PM in startups to larger companies. More about the role of PM rather than product itself.

Rules for Revolutionaries - Guy Kawasaki's book, half entrepreneur morale book and half how to create a product quickly.
