Lit by Mary Karr is a lively, impressionistic memoir of addiction and recovery. She bounces around, but most of Lit chronologically covers the two decades or so when Karr met her husband, deepened her alcoholism, had a baby, got sober, got divorced, and found Catholicism. At its best, the memoir captures Karr's interior turmoil in AA meetings and attempting to connect with God. This is true and vulnerable and interesting. Other parts of the memoir are so hazy (college, her husband) as to feel unnecessary when balanced with the rest of the book.
One of the blurbs on the cover of my edition praises Karr for being "unable to write an uninteresting sentence" (or something to that effect). That's an accurate review. A poet, Karr packs more into each clause than most writers. Something about that impulse, coupled with her gritty Texas aphorisms, didn't quite work for me. I found the voice taxing, especially during the vaguer sections of Lit. This criticism is subjective: I can see how many would appreciate Karr's commitment to originality. While my own taste bends toward the simplicity of Rachel Cusk or my boy Karl Ove Knausgaard, I would still recommend Karr's nonfiction, and let the reader decide.
