The Invention of Hugo Cabret by Brian Selznick

From chapters.ca:
Orphan, clock keeper, and thief, Hugo lives in the walls of a busy Paris train station, where his survival depends on secrets and anonymity. But when his world suddenly interlocks - like the gears of the clocks he keeps - with an eccentric, bookish girl and a bitter old man who runs a toy booth in the train station, Hugo's undercover life, and his most precious secret, are put in jeopardy. A cryptic drawing, a treasured notebook, a stolen key, a mechanical man, and a hidden message from Hugo's dead father form the backbone of this intricate, tender, and spellbinding mystery. With more than three hundred pages of original drawings, and combining elements of picture book, graphic novel, and film, Brian Selznick breaks open the novel form to create an entirely new reading experience. Here is a stunning, cinematic tour de force from a boldly innovative storyteller, artist, and bookmaker.
