A Primer in Positive Psychology by Christopher Peterson (late, formerly of U. of Mich.). It feels like very, very good undergrad university textbook (because that's what it is) but a very good, straight forward introduction to the topic. Very accessible, with lots of real world connections.

The Paradox of Choice by Barry Schwartz (Swathmore College). The subtitle, "Why more is less" sums it all up. Often have too many choices make us less happy, not more. Schwartz has a TED.org talk on this topic.

Authentic Happiness by Martin Seligman (Univ. of Penn). Seligman helped found of the positive psychology when he was president of the American Psychological Association. He has moved beyond the limitations of just looking as Positive Emotions (see my comments on the book Flourish on "Library, page 1) and the Flourish section of this website. But this is still an important book because it presents ways to understand our signature character strengths.
