Stretch your summer-reading session into fall and merge poetry, charity and style with local author Sorcha Duncan's Behind the Cane, a collection of inspirational poetry that offers a glimpse into Duncan's struggle with muscular dystrophy. Half of the profits get donated to the Muscular Dystrophy Association, but readers can benefit, too, thanks to a contest set in motion this past spring that will wrap up when book No. 3,000 sells. No purchase is necessary, but reading Duncan's work will help you answer questions on the entry form, which can be found at dragonriderpress.com , putting you in a drawing to win a half-carat diamond from Adolf Jewelers (Duncan's employer).
