Don't let its fluffy pink exterior fool you: There's some substance beneath that undeniably girlie cover. Which isn't to say that it's not predictable and formulaic. Aggressively confident Jocasta ''Cas'' Perry is a successful TV producer who prefers to live her life without attachments since her father walked out when she was 7. Now 33, she beds and discards men to keep them from leaving first. ''It's easier to enjoy the moment and not expect anything more because really there isn't anything more,'' she reasons. But after meeting gorgeous, morally upstanding Darren, Cas rethinks her M.O. Needless to say, love is found all around, but Parks handles it with such wit and verve that you don't mind indulging in such a guilty pleasure.
