7An ordinary day turns into an extraordinary adventure for three friends lying in the grass watching the clouds pass by as Zip, Trik, and Flip set off to find where the world ends. The trio journeys across fantastical landscapes--a lakeside city on stilts, a mysterious and magical forest, a snowy mountaintop--with countless delightful details for young readers to discover. Along the way, they encounter helping hands and discouraging doubters, and each time they think they have reached the end of the world, it seems to move further away. The three friends maintain their spirit and determination, enjoying the journey as much as the destination before returning home again.
