The cousins soon realize that for every friend they make on the boardwalk, there are also rivals, slummers, and frenemies who will do anything to ruin their summer-and try their relationship. Suddenly, Bella's not sure what she wants. Only problem: Bella can't get her romantic and ripped boss Tony 'Trouble' Troublino out of her head. In no time, she lands a job leading 'Beat Up the Beat' dance classes at a local gym, and is scooped up by Beemer-driving, preppy Bender Newberry. Finally free of her bonehead ex-boyfriend, she left home in Brooklyn with one goal in mind: hooking up with a sexy gorilla for a no-strings-attached summer fling. But is he tough enough to handle Gia when things really heat up? Bella is more than ready for some fun in the sun. Firefighter Frank Rossi is exactly her type: big, tan, and Italian. Luckily, she meets the perfect guy to help her keep the flames under control. Between nearly burning down their rented bungalow, inventing the popular 'tan-tags' at the Tantastic Salon where she works, and rescuing a shark on the beach, she becomes a local celebrity overnight. While they couldn't be more different-pint-size Gia is a carefree, outspoken party girl and Bella is a tall, slender athlete who always holds her tongue-for the next month they're ready to pouf up their hair, put on their stilettos, and soak up all that Seaside Heights, New Jersey, has to offer: hot guidos, cool clubs, fried Oreos, and lots of tequila. Giovanna 'Gia' Spumanti and her cousin Isabella 'Bella' Rizzoli are going to have the sexiest summer ever.
