The six non-fiction books making up the 2010 BBC Samuel Johnson Prize's shortlist have been revealed.
Alex's Adventures in Numberland by Alex Bellos, Barbara Demick's Nothing to Envy: Real Lives in North Korea and Blood Knots by Luke Jennings are among the titles hoping to win the GBP 200,000 award.
The shortlist is completed by Andrew Ross Sorkin's Too Big to Fail, A Gambling Man by Jenny Uglow and Richard Wrangham's Catching Fire: How Cooking Made Us Human.
BBC presenter, journalist and economist Evan Davis, the chair of judges, commented: 'We did have a number of arguments in our deliberations, but we've settled on an extraordinarily eclectic selection of books which defies simplistic categorisation.'
He added that the only common feature of the works included on the diverse shortlist is the authors' 'passion and sheer enthusiasm' for their chosen subjects.
The winner will be named on July 1st at an event at the Royal Institute of British Architects.
