Books I want to read if they only existed

1. A readable history of the Hanse, preferably by Jonathan Meades
2. A readable history of Guelphs vs Ghibellines, preferably by John Julius Norwich
3. A biography of the strange and intelligent Duchess of Newcastle. Maybe this exists, I don't know, I should look into it. It does exist and I enjoyed it: Mad Madge by Katie Whitaker.
4. A biography of Liselotte, who succeeded Minette as Monsieur's second wife at the court of Louis XIV, or a well-annotated collection of her letters.
5. A biography of the warrior queen Zenobia from Gibbon's Decline and Fall, though maybe there's not enough known about her.
