I am currently reading Passion by Jude Morgan (?).
It is about the lives of four women, but more importantly the men in their lives.
The men are up to now Lord Byron and Shelly. Keats is also to be included, although around 250 pages in, he has not yet made an appearance. Wordsworth has also been mentioned several times.
Other famous people who get a mention, "Mad" King George and his wife, Queen Caroline, Napoleon and Wellington.
It's not the easiest book to read, but it is a good read.
