The Midnighters Trilogy is a series of young adult science fiction books written by Scott Westerfeld. As the title implies the series contains three books, The Secret Hour, Touching Darkness, and Blue Noon.
The Secret Hour
Jessica Day (refering to Jonathan's sandwiches): But three of them?
Jonathan: That's nothing. Some birds eat their own body weight every hour.
Jessica: Sorry, I missed the feathers on you.
