If there's one thing that is known in magical Britain, it's that squibs can't do magic. At all. Everyone knows that.

The question is: how do they know that? Where did this certainty come from? The way the magical world works seems to be an inconvertible fact as immutable as gravity but the underpinnings of that world are built on sand and made of rotten wood.

When one Harry Potter is delivered to the hands of his oh-so-Squib Aunt, Petunia Dursley, it would seem that he would grow up ignorant, abused and desperate for anything that could save him from the mundane world. But squibs aren't what they seem, and neither is the magical world. What Harry discovers on his first trip to Diagon Alley changes far more than anyone might have expected.
