Yosser’s best friend Kylie has hair streaked with red and gold. She also has a belly-button piercing. Yosser isn’t allowed to streak her hair or pierce her belly button, but surely there are other kinds of fun she can have. When Kylie returns from the amusement park Thrill City, she's full of amazing stories about the best ride there — Sita, Snake-Queen of Speed. Sita is so fast and wild, says Kylie, that it sends an electric charge up her back and makes her hair stand on end! Yosser knows that feeling, and she knows that she must go on the ride. But there’s no way Dad will pay for such an expensive day-trip. Her only chance is to earn enough money to go. But how? An opportunity presents itself when Kylie’s dad’s prize ferret, Thunderball Silver the Third, mysteriously goes missing just days before the Grand Ferret Championships. Yosser and Kylie must find a way to catch Thunderball (and the thief!) and earn enough money to make Yosser's dream come true! Lively prose, quirky characters, and evocate illustrations distinguish this exciting multicultural story.
