Bad Girls in Love (Anne Schwartz Books) Reprint edition

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?
