Elif Shafak is an award-winning British-Turkish novelist. Her latest book, There are Rivers in the Sky, has just hit the shelves.
She has published 19 books; one was short-listed for the Booker prize and another was voted by the BBC as as one of the 100 books that shaped the century.
Elif joins Colin to discuss the new book - which is about one lost poem, two great rivers, and three remarkable lives - all connected by a single drop of water.
