Twelve year old Corey (Core) Riffen starts a garage band with his three best friends and quickly realizes that their band sucks – like a lot. It’s not their music or ever-changing image that’s the problem. It’s Corey’s lack of lyrics. He just can't think of anything cool to write about, until... he finds his older sister Trina’s diary. “Hey! This thing is full of teen angst and junk.” Core and the band ‘secretly’ use her latest diary entry for lyrics to their new tune – and what do you know? It sounds like pure awesomeness and the gigs are lining up! Problem solved right? Not exactly. Trina’s a total witch and can’t stand the thought of her little brother’s garbage band becoming more popular than her. She’ll stop at nothing to crush their dreams. But that’s cool. Core can read his sister, well… like a book. And he always knows just what to do to make her go diary and give them the one thing they’re missing…words! Follow Corey and his GROJBAND as they reach for the top. Gasp at the things they'll do to his sister’s fragile teenage world to get there.
