Hugh Kennedy - The Great Arab Conquests. (Pretty good.)
Sarah Dunant - In the Company of a Courtesan, and The Birth of Venus, which are research of a sort.
Sadie's biography of Mozart.
Alex Scarrow's Last Light - a trashy Peak Oil potboiler.
Craig Cheetham - The World's Worst Cars. About the worst cars. In the world. Ever. (Worth a tenner.)
