Would you rather be a girl who a stupid boy thinks is a boy even though she is actually a girl, or a girl who a stupid boy thinks is a girl and actually is a girl? Freddy knows what he'd rather be—anywhere but in front of Tabby. He's said the wrong thing and now he's not only hurt her feelings, but he might be uninvited to her awesome birthday party. It's going to be in a park with a jumping castle and a mechanical bull. Then Hugo, the new kid at school, tells everyone that Freddy is boring. It's the last straw. Yeah, well you pick your nose! So now Freddy's in trouble with everyone. Freddy will have to do something spectacular to win back his friends. He might be scared of heights, phobic about spiders and have nightmares about being naked in public, but he's not frightened of a mechanical bull. And he's got just the right costume. What could possibly go wrong?
