Crowning Glory of Calla Lilly Ponder (excerpt here), by Rebecca Wells, author of Divine Secrets of the Ya-Ya Sisterhood.
Return to Sullivan's Island (excerpt here), by Dorothea Benton Frank, author of Sullivan's Island and Isle of Palms.
And for those wishing for something non-fiction, this is one of my favorite books on Charleston and the definitive, truthful, work on chasing a low country family history to the land grant period: Slaves in the Family, by Edward Ball. Buy it and find brief reviews here, see the house where the Ball's live when you get there, and be privy to the family recipes in Charleston Receipts - yes, that Ball family.
Beach reading for those of you kicking back at IOP this summer.
