Martins Mean Mach/Katies Cust

Katie's grandpa helps her build her very own go-kart to race. On the other side of town, Marlon is preparing an amazing vehicle of his own. Both are determined to come first in the race, and only you can decide who wins! This is a double-sided book with a pop-up go-kart track at the centre, and two magnetic karts for you to race.
