Continental divide

the long version

"Moving on to higher things from his job in a community college, former sixties activist Michael Bern finds that his partner has thrown a surprise fifty-fifth party in his honour, at which she and his friends present him with his FBI file (with dramatized extracts, of course). In the file, Michael finds proof that one of an eight-strong group of activists was an FBI informer. His career and relationship threatened by his discovery, Michael sets forth to find the eight, a quest which takes him from a political campaign to a ghetto neighborhood, from a gated community to a beachside fundraiser, from a group of hippy treesitters deep in the redwood forests to the site of a vital governor's debate. On the journey, Michael discovers what happened to his former friends, but more profoundly, what has happened to himself."--Publisher's website.
