Kindred Spirits is a short story released for World Book Day and it's the story of Elena, a girl who decides to sit in line and wait for three days when The Force Awakens comes out at her local cinema. She meets two other super Star Wars fans and they basically sit and shoot the breeze while they're waiting and learn something about themselves along the way (well, Elena does).
This really struck a chord with me because although I didn't wait in line for three days (because I don't want to get fired from my job) my family and I were incredibly excited when the new Star Wars film came out. We're a whole bunch of nerds in my house.
Anyway, Rainbow Rowell somehow manages to spin out a story from basically three people sitting in a queue waiting for The Force Awakens to start. Not sure how she did it, but it's totally, totally readable and I'd definitely recommend it if you've enjoyed any of her previous works.
