Never break the rules. Especially if you have absolutely no idea what they mean. Over the course of one unforgettable summer, two boys must navigate a mysterious set of arbitrary laws governing their relationship. You must never eat the last olive at a party. You must never ruin a perfect plan. And whatever you do, never give your keys to a stranger. As the older brother invents the rules, the younger brother tries his best to follow along, leading them into an emotional landscape that is both bizarre and oddly familiar. Their adventures push them to hide from a giant, glowing red rabbit and outwit a terrifying crowd of mechanical eagles. But as their games stretch further and further, the consequences of breaking the rules become darker and far more sinister. A simple mistake can turn the sunny days into a surreal, unsettling nightmare where winter comes rushing in. This deceptively simple narrative pairs sparse, poetic text with exquisite, mind-bending paintings. It explores the confusing, sometimes devastating ways we interact with the people we love most, building toward a redemptive ending that affirms the inexplicable, powerful bond of true friendship.
