The book is about the hip teenage girl from London named Isobel Foster (or Izzie if you like). Together with her best girlfriends, Lucy and Nesta, she experiences the unexpected opportunities and letdowns with being a teenager. She gets in trouble, makes unwise choices and falls head over heels for the most handsome boy in town. This is where the real conflict in the book begins, when Izzie gets to know what boys are and what they actually are able to do with the girls’ feelings. After her first sight at Mark, which is the name of her lover boy, Izzie can’t think of any other thought than him. They met at the mall, exchanged telephone numbers and Mark told Izzie he would promise to give her a call. But, in Izzie’s desperation, he never gives her the wanted call, which makes Izzie go insane. All she can think about is this Mark. All she talks about is Mark and how cute his blue eyes are and how nice his brown hair is. Everything she does, she does in preparation of getting the call from Mark. Izzie stops spending her spare time with Lucy and Nesta, just in case Mark calls on her phone at home while she’s hanging out. She gets desperate after his call, and suddenly the phone rings.
Further on in the book Izzie has problems with Mark, and after a while back and forth she finally admits to herself that he’s not that interested as she thought at first. In the end she dumps him, and promises to herself that she’s never going to fall for a stupid boy with cute, blue eyes ever again. As soon as spoken Izzie meets another guy named Ben, who seems unusually kind to be a boy. They get along well, and exchange telephone numbers after a while, but this time Izzie tells Ben that she is the one who is going to make the call. She has turned the game upside down, and will never wait for a boy to call ever again.
