From New York Times bestselling authors Garth Nix and Sean Williams, comes this hilarious, action-packed adventure featuring a very unlikely knight, an admirably stubborn girl, and a sword with attitude.
When Odo and Eleanor stumble upon an ancient sword in a river outside their village, something very unexpected happens... the sword starts to talk! Much to Odo's dismay he discovers that he's awoken a famous enchanted blade called Biter, and thus has instantly become a knight.
Eleanor would love to become a knight but she's not the one with the sword. Unearthing Biter is only the start of their troubles; soon boy, girl and sword must depart on a noble quest to save their kingdom from threats - in both human and dragon form.
