Jean Valjean was sent to the Toulon prison in France for stealing a loaf of bread to feed his sister’s family. He attempted to escape from prison five times, which led to a 19-year sentence, and had finally been discharged.

The only luxury items that he had in the house were some fine silver plates and candleholders, which he did not keep locked up.

Free Essays on Les Miserables Book Review for Les Misà ©rables, by: Victor Hugo â€Å"The book, Les Misà ©rables by Victor Hugo is a book of undeniable passion, a love of humanity, and freedom for one’s country. It celebrates, an amazing epic scale, the life of the poor people, the working class, and the condemned. It tells the story of an extraordinary fight for independence and happiness.

I believe the thesis is well written, because it pinpoints Hugo’s main theme of the novel. A strong point in the novel is Hugo’s point of view. Not only does the book tell a fascinating and riveting story but Les Miserables is like a historical document of the rather miserable times of the 1800’s in France.
