Hugo Cabret is the son of a clockmaker. He was being raised by his father until his father died in a fire. Hugo's uncle Claude then took Hugo to live with him in an apartment located in a train station. Uncle Claude's job at the train station is to maintain all of the clocks in the station. Hugo becomes Uncle Claude's apprentice but when Uncle Claude doesn't come home for several days (or ever again), Hugo continues to take care of all the clocks by himself. Hugo becomes intrigued with a toy shop in the train station and keeps a stash of toy parts that he pilfers from the shop. From these parts, he is able to rebuild the broken automaton machine that he found in the wreckage of a museum fire. He is convinced that the automaton holds a message for him from his father. The inventor of the automaton surprisingly ends up being someone that Hugo knows. The one hundred and fifty eight illustrations in this book are spectacular and tell the story with as much power as the words do. So what is the invention of Hugo Cabret? You will be amazed when you find out!
