A new book to read.
 I was at work & this book was in a clearance basket near to the till where I serve customers & the book seemed to call out to me to take a look; after reading the blurb I felt compelled to buy it for 80p.
"Five days in a Frozen City.....Strangers fall in love, wishes come true & life will never be the same again".
