Mikey and Margalo are prepared for battle. Watch out, because the bad girls just got worse!; When it comes to being bad, Mikey and Margalo pretty much rule the school. But a new term has started, and things aren't quite as they should be...Mikey is trying to be nice. It's a tactic - she hopes that it might persuade her parents not to get divorced. It doesn't seem to be working. And being nice puts a lot of stress on a girl who prides herself on being anything But. Then Gianette comes along. She looks like sugar and spice and all things nice. But she's so bad, she's in a class of her own. Two bad girls were bad enough - is the world ready for three? The funny, fast-moving sequel to Born to be Bad by Newbery Medal winner, Cynthia Voigt.

THE BAD GIRLS ARE BACK! NOW THAT THEY'RE IN SEVENTH GRADE, Mikey and Margalo decide it's time to be popular—or at least, time to be less un popular. The trouble is, typical, normal kids are what work in junior high, and if there's one thing Mikey and Margalo aren't, it's typical and normal. Mikey's first attempt to crack seventh grade society ends, predictably, in disaster, but, undaunted, the friends persevere. They've got the will, they've got the smarts, and most importantly, they've got each other. What chance does junior high have against the Bad Girls?

Look out! Mikey Elsinger's in love! Mikey never does anything halfway, so it's no surprise that when she develops a not-so-secret crush on Shawn Macavity, the heartstoppingly gorgeous star of the school play, she goes a bit overboard. Soon Mikey—Mikey? — has a stylish new wardrobe, and she's baking Shawn cookies, writing their initials on blackboards, even buying him a T-shirt emblazoned "I LOVE ME." Fellow Bad Girl Margalo tries to get Mikey to turn things down a notch, but why should Mikey listen to her? — after all, what does Margalo know about being in love? Or is Margalo hiding a romantic fantasy of her own?

Mikey and Margalo: Bad girls. Best friends. Big trouble...Mikey Elsinger isn't the romantic type. She thinks that most boys are just brainless meatheads. Girls who like brainless meatheads are too weird for words. Margalo Epps likes to admire boys from afar. Maybe a movie star, or even (don't tell anyone!) a teacher. But most of the boys at school stink (some of them literally). Enter Shawn Macavity. Technically, he's a brainless meathead. But he's gorgeous. Really, really gorgeous. Thwack. Cupid's arrow strikes its target. The world has changed for ever. Mikey is in LURRRVE. And Margalo is NOT impressed...The fourth funny, touching book about bad girls Mikey and Margalo
