In Secrets of the Tulip Sisters by Susan Mallery, the return of a wayward sibling psets life down on the (tulip) farm.  The Almost Sisters by Joshilyn Jackson offers more sisterly drama, southern-style.  Beach House for Rent by Mary Alice Monroe, which  reprises the ‘strangers meet and bond at a seaside retreat’ motif, vies for the  crown of Beach Read Queen.  In Cocoa Beach by Beatriz Williams, a widow in prohibition-era Florida has reason to think her rakish husband was a bootlegger.
