Each June, for “Novel Ideas,” a business or organization reviews a selection of books in a variety of genres. Several Washington service groups are doing the honor this year. These individuals, be they a Lion, Optimist or Rotarian, possess a common denominator — each is a self-professed book lover. The clubs they belong to also share a bond, a commitment to community and to literacy. Here’s hoping you’ll find your next great read in this special summer feature.
