Twelve-year-old Strobe Bevan-Evans only wanted new blades and a trick to impress her snobby classmates. She never expected to chase a one-metre cheesecake--and a pair of art thieves--at ninety kilometres an hour.

When Aunt Olwyn's spectacular engagement banquet ends in disaster, the social pages blame Olwyn for the vanished dessert ... and four priceless paintings. To clear her aunt's name, Strobe teams up with pizza-delivery blader Winston Wong, camera-mad Alex Wong, and accounting prodigy Tran Nuen. From half-pipes and city traffic to a frantic airport showdown, the kids flip, grind and custard-chucker their way through a mystery packed with laughs, friendship and guts.

Can one fearless skater and three loyal friends turn the city upside-down before the real thieves escape--cheesecake crumbs and all?
