The third compulsively readable book in the smart and witty series about a high school for gifted students. Miranda Bloom has scored an adorable, lacrosse-playing boyfriend, Dex McConnell, and an awesomely easy summer job looking after a ten year old mini-genius, Amelia. This summer is going to be sweet... Then reality puts the brakes on everything. Though Dex and Miranda are official, she feels like he's keeping secrets-secrets that may have to do with his fashion model ex-girlfriend. Meanwhile, Amelia is harder to figure out than advanced trigonometry. How can they bond if all she does is practice the piano? Plus Miranda's mom just invited her to live in London with her. Living across the pond would be great, but can she really leave Geek High and Dex? Looks like Miranda has a secret of her own...
