it was a good thing my sister was n't there . it was already starting to feel more natural . but when he raised his head , his face was grave . jack looked up from where he was still sitting in his uncle 's study . or no longer worrying that next time i take a step it might be my last . it made the whole structure wobble . his father did say it would calm down , but when ? i bit my lip , and looked at him . mercer barked ; then he was running toward them .
