A Great and Terrible King: Edward I and the Forging of Britain by Marc Morris (nonfiction 2009)

Edward was an amazing man, very long-lived as well as long-limbed.  This book follows the ins and outs of his adventurous and global life, and it does a great job of connecting the threads of his experiences throughout time.  Highly recommended especially for the attempt to put Edward's more notorious acts in the context of the times.
