It is amazing how far your mind can go just by reading a book. And you can pick which way you would like it to go. For instance: You are on a battlefield and the enemy is on your tail; your best friend has been shot. Do you have the strength it takes to get to safety along with your friend before the enemy reaches you? Or how about you are in a magical world with wizards and mages; in order to save one of the wizard's from peril, you are sent on a journey to gather everything you need for a potion that only a witch can brew to save it's life? Along the way you encounter many enemies to stop you.
All you have to do is dive into a book and be swept off your feet.
