If you fancy having the chance of picking a winner and having a say in which book is named Costa Book of the Year, "...all you need to do is submit a book review and give a good reason why you'd make a good judge. If you win, you'll attend the gala presentation awards ceremony in January 2009 and brush shoulders with giants of the literary world."
Full details HERE.
Good luck and if you win, mine's a double macchiato. Ciao. :0x
