There's a reason that the number thirteen is bad luck: it sucks to be thirteen. You're definitely not a kid anymore, but your parents still treat you like one. No-one escapes thirteen unscathed - not even the best looking, most popular people with straight white teeth. The best you can do is be true to yourself, even when everything's changing. Girl v the World is a funny and inspiring series about thirteen-year-old girls taking on the world. Because you've got to be strong to take it on! Lenni can't please anyone lately. At school, her friends want her to kiss someone for a stupid competition. At home, her grandmother wants her to be more ladylike. And on the athletics field, her friend Adam has started acting like a big weirdo around her. Then Lenni meets Jo, the new girl at school, and everything feels so normal. Jo is cool and fun, and unlike anyone Lenni's ever known. Finally, someone's on Lenni's wavelength!
