A short but very engaging overview of the troubled reign of Edward II. Very easy to follow, despite the wealth of material it has to cover, and relatively balanced, offering multiple perspectives on the king's behaviour. I particularly liked the attention paid to Gaveston and Despenser; there's no pretending that they were definitely just bros and pals, but there's enough room here for nuance and the suggestion that their relationships were difficult to define. The further reading suggestions at the end are great, too.
Also, on a trivial note, I had no idea that Hugh Despenser was so annoyed at being exiled that he decided to become a pirate for a year. What a terrible, awful, brilliant chap. As a Welsh person, I absolutely hate him, but as a morally complex gay, I respect him.
