Morris Lessmore loves words, stories and books; after a powerful storm carries him to another land, dreary and colorless, he finds a single book in color that leads him to an amazing library where, he learns, the books need him as much as he needs them.

Before Jack Frost was Jack Frost, he was Nightlight, the most trusted and valiant companion of Mim, the Man in the Moon. But when Pitch destroys Mim's world, he nearly destroys Nightlight too, sending him plunging to Earth where, like Peter Pan, he is destined to remain forever a boy, frozen in time.
