An authoritative look at Judaism's historical sweep and distinctive religious dimensions, showing how it developed out of the Hebrew Bible and has diversified throughout history and throughout the world.
Looked in here to find out whether Jews believe in an afterlife (and I still don't know). More a social history of the "movement" rather than an explication of its tenets.
Summarizing Judaism in less than 150 pages is no easy feat, but Michael Fishbane does it expertly. If you're looking for a concise treatment of the traditions, beliefs, and practices of the Jews, this is your book.
