Karolyn Smardz Frost has a new book out with Thomas Allen Publishers: I've Got a Home in Glory Land. Haven't read it yet, but sounds like one to read. It's a microhistory of John Blackburn, an escaped slave and 19th century Torontonian, apparently in extraordinary detail.
KSF is an archaeologist, ED of the Ontario Historical Society, person-about-Toronto-history for a long time. Apparently she's been working on this some twenty years, and the book grows from a doctoral dissertation. Good on her.
