When strange late-night letters start arriving at home, and Emily's parents disappear completely, she takes all of the clues at her disposal and makes for the place where the letters came from — the mysterious Night Post. What she'll discover is the secret world of the Midnight Hour — a Victorian London frozen in time, full of magic and monsters. Kept safe by an age-old agreement, the Night Folk have been exiled to a parallel world that can only be accessed by a selected few, including the mail carriers of the infamous Night Post that operate between the two worlds.
Emily's parents are key players in keeping the Night Folk safe, but when the division of the two worlds is threatened, Emily must search for her parents while navigating this dark and unknown version of London, armed only with a packed lunch, her very sleepy pocket hedgehog, and her infamously big argumentative mouth. This is a frightening and enchanting story set in a world built out of creatures from our worst fears, perfect for fans of Nevermoor and Wildwood.
