So I'm was talking with my Mum, about how i fancied reading Wuthering Heights again...  A week or so later in she steps, with a copy she had found in a coffee shop in the city centre (Manchester).. on the cover a yellow sticky note reads...
 "I'm Free! I'm not lost! Please pick me up, read me, and help me with my journey! (see inside)"
I was Aware that people often left books in coffee shops and the likes off but... To put it simply, I am delighted, and amazed by this whole website which documents the sharing of millions of books across THE GLOBE. Top notch... Check it out.
