Where it came from

Every country in these books was founded by decent people after something terrible. A plague winter in which neighbours died behind locked doors. Centuries in which bread went by surname and judges were bought. A war that ended only when a generation agreed to stop remembering it.

Each country answered its wound with one law, and each law is a good one. No one should be treated arbitrarily. No one should suffer alone. No one should be punished for an honest mistake. You could put any of them on a wall. Most of us would sign.

The books ask what happens next. A law that prevents one harm has to be enforced, and enforcement needs instruments: a scale, a census, a court, a clerk with a form. The instruments are kind, mostly. The people who run them believe in them, and they are usually right to. Then someone walks in whom the instrument cannot read.

The man who counts

The traveler at the centre of the series was a ledger clerk before the crossings began. He has no name, and no country ever manages to give him one. What he keeps is the habit of accounts: he notices prices, weights, who owes whom, and what a kindness costs and who ends up paying it.

He does not explain the countries, and he does not fix them. He writes down what he sees, fairly, including the defences of laws that hurt people, because the people defending them mean every word. That is the whole method of the books: set a good law down in a real place, and count.

What the books leave to you

There are no villains on this map, and no verdicts. Nobody gives a speech about what it all means. The countries are allowed to be right about what they fear. The question each of them leaves is the one we keep meeting in our own offices, courts and apps: when a rule is built to protect people, what does it cost the person it was never built to see?

Twenty laws

The full list is on the countries page, one law per country, four countries per book.
