Boston book clubs

I've been looking for a book club to join in the Boston/Cambridge/Somerville area without any success. Anyone have any suggestions (besides starting one of my own)?

I think the Somerville library has a book group?

I'm in a literary bookclub which alternates meeting in Watertown, Brookline, and Somerville. A very smart and welcoming group -- this month we're reading Michael Cunningham's Specimen Days. Email me at verbify at livejournal dot com if you're interested.
