Sydney thinks her mother Amy is the best mom in the world—even if she is a bit . . . different from other kids' parents. As Amy explains it, when she was a girl she got to 48 inches tall and then stopped growing right there.
It's the perfect height, in Sydney's opinion: big enough to reach the ice cream at the supermarket, but small enough to be special. Anyway, Sydney's big sister Jade is always there to help out with the stuff on the highest shelves. And though Sydney's dad died when she was only five, she's never felt alone or that there isn't enough love to go around.
But when they are forced to move to another neighborhood, things get more difficult for their little family. Sydney and Jade have to get used to different routines, make a whole new set of friends, and deal with the bullies at their new school.
And then there's the whole business of growing up. But Sydney doesn't want to grow up—not if it means getting taller than her mom.
