Grace Parker tries to figure out how to handle the 3Bs: boys, boy bands and ball sports.

Things were simple for netball nerd Grace Parker at primary school. She was captain of her school team - and with her best friends, Stella and Mia, by her side, they won the grand final. Back then, her biggest problem was persuading her parents to buy her tickets to see Friday at Five, the world's hottest boy band.

But high school's a whole new story ... Grace's greatest rival on the court, Amber Burns, just made the same netball team as her. Her twin brother, Gus, is devastated he didn't make the A-grade AFL side. Her older brother, Tyler, is ignoring her. And as if that wasn't enough for a 13-year-old girl to handle, gorgeous aspiring rockstar Sebastian King is suddenly paying her a lot of attention.
