Two boys explain the occasionally mysterious "rules" they learned over the summer, like never eat the last olive at a party, never ruin a perfect plan, and never give your keys to a stranger.

From the NEW YORK TIMES bestselling author of THE ARRIVAL

Never be late for a parade.
Never forget the password.
Never ruin a perfect plan.

It's all about the rules. But what if the rules feel completely arbitrary? What if your older brother is the only one who gets to make them up all summer long? And what if he's the only one who can save you when the darkness of winter comes rushing in?

As usual, master artist and storyteller Shaun Tan shows us the strange truth of ordinary things -- rules, relationships, despair, and hope -- as only he can.
