That is until, one early morning, when Fortitude finds Patience is missing. The city is about to awake, and the lions absolutely must be in their places before the sun rises. Now, Fortitude must abandon his own post to find his best friend in the Library's labyrinthine halls.

With Josh Funk's clever rhymes and Steview Lewis' vibrant art, Lost in the Library introduces young readers to a pair of unforgettable lions, as well as the famed New York Public Library, and includes bonus material loaded with facts about Patience, Fortitude, and the NYPL's history.
