I advise those perusing these reviews to take with a measure of salt the dogmatic pronunciations on the quality of Rose's translation. Provenance is important, and one should always "consider the source." (Yes, even with me.)
A number of interviews with Rose are available online, in which she discusses her work, and her work on this novel. The novel has a lengthy and detailed Translator's Preface, in which she discusses the novel, the translation process, and her approach to it. You also can find online some independent articles about this translation.
The great translator of Spanish language literature, Edith Grossman, said:
"I can't say what makes a book translatable, but I do think that all texts can be translated. The question of whether or not a work is "translatable" stems from a mistaken and widely held notion that a translation is really a one-for-one set of equivalences with the original--a straightforward lexical problem--when in fact it is a rewriting of the first text. Some, of course, are immensely difficult (they're usually just as difficult in the original) and challenge the translator's sensitivity to nuance, levels of meaning, and artistic impact in both languages. I see my work as translating meaning, not words."
Rose has spoken similarly about her work.
"I think the essential difference is that...and I'm not saying that translators always have to do this, there are reasons for departing a little bit further from a writer's text where it just won't work in English. I found on the contrary what really worked better in English was to follow Hugo much more closely than anyone else seems to have done. So I've actually followed his syntax as closely as possible, I've followed the rhythm of his sentences and I've actually broken it up the way he has and stuck more closely to what he says." -- Julie Rose, interview, 2009
She's translated more than thirty French works into English -- plays, poetry, novels, genre fiction. She worked on Les Miserables for three years. She has been awarded three international prizes for her translations. I'm willing to take the leap of faith -- she is "fluent in French." I recommend others accept the facts in plain sight, and do likewise.
I stopped reading works in translation in the early 1980s, and didn't start up again until around 2005. The reason I stopped was that I concluded that I could not hear the author's voice in the translated work. The reason I started again was that Rose, Grossman, and some others showed that they understood this challenge, accepted it, and that it is possible to capture the author's voice in a translation, by actually listening to the author's intent.
According to one account, the Rose translation is almost 100,000 words longer than the 1976 Denny "translation" -- that's how much material he excised from the novel to "improve it." Denny, in fact, is on record as saying that Victor Hugo was a terrible writer, and needed some "tidying up." If you're just looking to pad your reading CV with another of the "great books," then it doesn't matter which one you read. Might as well go with a shorter one. If you're looking to read the translation of Les Mis, that will make you feel like you are reading the original, hearing Victor Hugo's voice, then pick up Rose's translation.
''When I was 15, I was completely bowled over by Les Miserables. All my life long I have continually been discovering fresh aspects of Hugo's genius.'' --Andre Maurois (French author 1885-1967)
Les Misérables (1862) is a novel by French author Victor Hugo, and among the best-known novels of the 19th century. It follows the lives and interactions of several French characters over a twenty year period in the early 19th century that starts in the year of Napoleon's final defeat. Principally focusing on the struggles of the protagonist—ex-convict Jean Valjean—who seeks to redeem himself, the novel also examines the impact of Valjean's actions for the sake of social commentary. It examines the nature of good, evil, and the law, in a sweeping story that expounds upon the history of France, architecture of Paris, politics, moral philosophy, law, justice, religion, and the types and nature of romantic and familial love. Les Misérables is known to many through its numerous stage and screen adaptations, of which the most famous is the stage musical of the same name, sometimes abbreviated "Les Mis" or "Les Miz" .
