Authors with last names starting with "U"

[Travis]

As a 2013 challenge in a different book group I will be reading a book from each letter of the alphabet used as the authors first letter of last name. I have searched listopias and recommendations, but I cannot find any authors last names starting with "U". Any suggestions would be appreciated. The books must be 200 pages or longer so any short childrens book authors will not work. Help and thanks

John Updike

John Updike - he won the Pulitzer Prize for fiction twice. Once for Rabbit Is Rich and Rabbit at Rest. Might be a good place to start!

Leon Uris -- Exodus is my favorite, but he wrote a lot of great books.
