Ok, so I have a very specific criteria to choose Books to read. I usually don't read much except when I am travelling long Distances. 

I First check the Name of the Book and it's author. The Title is a key factor for me, then I go in and have a brief look inside the Book and look for specific characters. The more the uncommon names I find the more I am interested in it. Lastly there is the price tag. Hehe Price is also important my Friend.
