So if you know anything about De Quincey, it's as the guy who wrote "Confessions of an English Opium Eater." Understandably so, given that so much of his writing was for magazines.
His life is a pretty fascinating cautionary tale though, given nearly life-long addictions to opium and alcohol and prostitutes (?), it's amazing that he managed to provide for a family of seven children (admittedly not very well) and write the amount that he did write. His sounds like a pretty typical story of what addiction does to a talented person, but atypical in the sense that he didn't crash and burn, he managed to nurse that addiction and his talented intellect, his failing body and utterly cripplingly bad finances - seriously, horrifying to read about - to the end, while producing some very well-regarded work.
Reading this book, for me, is like reading a cookbook without wanting to cook the food. I don't come away wanting to read De Quincey, but I was fascinated by the pattern of his life. He must have been a really charming guy and you have to wonder what his legacy would have been without the laudanum.
