I'm not sure that any book has ever truly changed my life in the sense of dramatically altering its course, but I can think of one that determined it, and that's Palgrave's Golden Treasury of the Best Songs and Lyrical Poems in the English Language. It was my mother's book and she read to me from it, as I imagine, in the dark. It was from Palgrave that I learned that literature had a sound, that language mattered more than story, that rhythm haunted the imagination, and that love and grief and loneliness interested me more than any other subject.
