написание имен исправлено, кое-где перефразировано чтобы читалось лучше

роман по английски не "romance" (это значит роман только в смысле любовь), a "novel" (в значении книга)

magician исправлен на wizard, т.к. в английском оригинале книги именно это название волшебников (в женском роде witch)

p.s. гермиона вполне себе волшебница, так что "she wasn't a magician" не совсем верно технически :) если имелось в виду, что ее родители маглы (не волшебники), то исправлено на "her parents weren't wizards".
