Dorothy Baker's Cassandra at the Wedding is an ideal summer read. It's a somewhat forgotten classic that is simultaneously high comedy and tragedy. When her twin sister Judith intends to get married at their childhood home, Cassandra does everything in her power to sabotage the wedding. But this isn't a schlocky, Matthew McConaughey-starring rom-com. Cassandra's attempts are funny, yes, but also call to mind questions of identity and sexuality. Simply the most fun you'll have this August.
