Title: Midnighters #1: The Secret Hour by Scott Westerfeld
Genre: young adult, horror, sci-fi
Comments: When 15-year-old Jessica Day moves to Bixby, Oklahoma she discovers a 'secret hour' at the stroke of midnight when time stops for herself and a handful of others born at true midnight. At first it is exciting exploring the world and discovering the secret powers each 'Midnighter' has. But there are dangers and dark forces also inhabiting the secret hour - and they seem to be especially interested in Jessica.
