The Trusted Five
You pick five: Tilly, who can paint anything and once kept the secret of her sister's surprise party for six months, which in this town is a world record. The Okafor brothers, package deal, drum kit included, silent as owls when it matters. Priya of the four hundred jokes. And Old Wen's grandson Milo, who doesn't talk much, and notices everything, and once carried an injured hawk two miles inside his coat.
You tell them everything except the word unicorn — and then, because trusted means trusted, and because Sera insists (“if they're to fight her war, they'll know who for”), you tell them that too. In the cellar, by lantern light, five children meet a guardian of the dawn, and the reactions go: paint-stained hands over mouth; both brothers, in unison, “whoa”; a joke that dies of wonder halfway out; and Milo, nodding slowly, as if a very old suspicion about the world had finally been confirmed.
Five is not an army. But five who know why — who've had a unicorn breathe on their hair — fight like fifty. The Brightness Brigade is small, and it burns hot.
