Looking for Suggestions

I’m looking for some help.  I’ve got an idea for a family bonding experience.  Our get togethers aren’t as lively as I’d like, and usually I’m placed at a dinner table next to my dear step-grandma, an intelligent, kind woman, who loves to tell me all the latest antics of people I’ve never met.  She gets offended if I interrupt to say, “Now, who is Randy again?” and she’ll say, “Don’t you remember?  He’s Kenny’s 2nd cousin’s husband, the one from Fresno?  With the son who is a blackjack dealer in Reno?  I mentioned him at Christmas!” and then she resumes the story as my eyes glaze over, not daring to ask who Kenny might be.

So, back to my idea.  There are 8 of us- 4 couples- ranging in age from 29 to 87.  Three of us, including the oldest two, are Japanese Americans.  The oldest couple are first generation Japanese Americans who actually remember being in the internment camps in Central California during World War II as children.  The youngest of us is my brother’s longtime girlfriend.  She is a first generation Chinese American.  4 of us grew up in California, the rest of us are transplanted midwesterners with WASP-y heritages. The women and one of the men love to read, the rest are reluctant readers.

My idea is that I’d choose a book for all of us to read and discuss.  I’d give the books out as gifts on Mother’s Day (the next time we’ll all be in the same room at the same time) and we’d discuss the book on Father’s Day.  The reluctant readers might receive an audio book.

My dilemma– what book would appeal to a group with such wide differences in age and backgrounds? Does a book like that exist?  I’m looking for suggestions.  Please let me know what you think.
