I took advantage of the Easter Break to chat with many of my friends from college; by far the most interesting in publishing terms is Sam Collins a Chess player of some repute and also a chess writer with three titles to his name.
Now chess has never been my game but he has shown himself to be adept both at playing the game and writing titles that appeal to beginners and more advanced players. He told me that one of his books is due to go to reprint soon and that they will be translated into German and Spanish.
You can see his books here or visit a profile here. He is currently studying in London and in September is due to join Boston Consultancy Group.
