A girl in room 105 is a thriller novel written by chetan bhagat.However story is thriller but very much predictable.My guess about the killer was absolute right but I was wrong about reason why she was killed.
The story is about a girl named zara lone who was murder in IIT delhi campus in her own hostel room.Before dying , she calls her ex-boyfriend kesav into her room who finds her dead.kesav makes it his life's mission to solve her mystery and his friend saurabh helps him in that.
So if you love suspence or thriller stories you can prefer this one.
