Understanding the Universe: From Quarks to the Cosmos, Don Lincoln
Lightness of Being, Frank Wilczek
The Particle Garden, Gordon Kane (University of Michgan colleague)
Antimatter, Frank Close (good public writer, and theoretical physicist)

The Particle Odyssey, Frank Close, Michael Marten, and Christine Sutton (really nice historical account with lots of photographs)
The God Particle: If the Universe is the Answer, What is the Question? Leon Lederman (nobel laureate, former director of Fermilab and friend of many of us. To me: the best account of what it is like to make a major discovery)
Warped Passages, Lisa Randall (theorist at Harvard who has come up with maybe the most sensible string-approach to particle physics)
Physics in General
