Do you have a published book about Canadian history? The magazine Canada’s History has an online form where people can post 150-word [or less] reviews of such books. http://www.canadashistory.ca/Books/Book-Reviews/Share-your-favourite-reads.aspx . They don’t guarantee they’ll publish them, but you might ask someone to post a review of yours there. In the form they also allow 200 characters for the reviewer to tell something about him/herself.
