Motion Commotion (Paperback) (ISBN-13: 9781458207609)

Siblings Adam and Krystal go swimming by their house, and while skipping rocks, they make an incredible discovery: the rocks don't skip but bounce right into the sky! So begins a day of disorder. With the help of Great Granny Franny Force, the children discover that King Chaos is trying to take over the world and turn it completely upside-down.

In order to stop this evil king, Adam and Krys must travel to the world of Chaos, overcome its dangerous hazards, and rescue a dear friend from the dreaded king's castle. Along the way, the children learn much from Grandpa Gravity, his friend Newton, and a trio of sisters with subtle differences among them-Alice Acceleration, Vicky Velocity, and Samantha Speed.

With the help of their new friends, Adam and Krys might just succeed. But King Chaos is full of tricks; using his terrible henchman, Hap Hazard, the king could turn the children's world of order into a cataclysm of chaos. Adam and Krys are humanity's only hope, but can they navigate Chaos, or will they get lost in a world without order?
