Someone bought me Richard Holmes' new biography of Tennyson – The Boundless Deep. Finished it today. Wonderful book. I know Tennyson seems dull compared to poets like Byron or Ted Hughes, but it isn't exactly a biography. It's more about the ideas swirling around him. It's fascinating to read about these Victorian figures struggling with dinosaurs and evolution and the age of the Earth and the vastness of space, etc.
I'd really recommend it. Holmes isn't a dry or heavy writer. He reminds me a bit of Bill Bryson.
