Suggest me an easy read, fun, interesting book that would keep me entertained and busy for my 36 Hour Plane Journey.

As the title says, I'll be travelling this month and will have long layovers and a long flight duration. I want to take a few books with me on this trip. So far, I bought "A thousand Splendid Suns" . Because on my last journey I was kept busy and entertained reading " Kite Runner"
