Luminous Passage: The Practice and Study of Buddhism in America

Berkeley, University of California Press: 1999.

Another scholar-practitioner, "Prebish gives us not only the mature thought
of someone who has been on this road awhile, but also plenty of narrative
into the history and progressive re-envisioning of his own understanding
of the subject.

(David L. McMahan; see his whole review: PDF format; HTML format.)

This is not a comprehensive survey, but treatment of selected topics, including sexual and gender issues, and the phenomenon of "cybersangha." Moreover it's not a general introduction; you need some familiarity with terminology and traditions, to follow his thought.

After reading McMahan's comments, I'm looking forward to seeing what Prebish has to say.
