After a mysterious event transports him to who-even-freaking-knows-where, a young man must survive in a dangerous world he knows nothing about and which is populated by life forms that can quite easily kill him. In order to have a chance of survival he'll have to trust in his own wits and an attractive native of the new world in which he is stuck. Perhaps he is also the Destined One who is foretold in prophecy to be the one who will save the world!*
*Note: Protagonist is not actually the Destined One who is foretold in prophecy to be the one who will save the world.
