'Join three friends as they use their imagination, settle playground scores and alter the entire course of history in the process!
'Sid's schoolyard nemesis, Zachary Black, has stolen the most awesome comic Sid and his evil-genius neighbour, the Mighty Professor Skeletron, have ever made. Zachary sets Sid a challenge – beat him in an arm wrestle and the comic is theirs once again.
'Sid and Skeletron calculate Sid's chance of victory as 1 in 10 so they create a Time Rescrambler in order to allow Sid to take the challenge ten times . . . and eventually win! But on one occasion, Sid's sister, Wendy, hits the rewind button too hard and the trio are transported to the Mongolian plains in the year 1180. To make matters worse, the device falls into the hands of a great warrior.
'Will they save the world, or will life as we know it no longer exist?' (Publication summary)
