The Dalai Lama has many excellent books on Tibetan Buddhism, my favorites are How To Practice: The Way to a Meaningful Life and Open Heart: Practicing Compassion in Everyday Life.

 

Lama Surya Das, Traleg Kyabgon, and Thubten Chodron all have excellent introductions written from a Tibetan perspective as well.

I started with the Dalai Lama's An Open Heart. It is fairly simple, and starts out with a very general theory of what makes a healthy, good life.
