Timeless

After Jake walked into class and talked to his best friend. He pulled out his new notebook. He bought it on the internet by an anonymous user. A poem was written in it.
In these pages contain a gift to man forgotten.
But it is a curse, a blessing, and neither at the same time
It is godly and something that should not exist
Be warned a single mistake could mean death to the user....
Later that day something else happened he fell asleep and woke up to be in some sort of apocalyptic future but as he will find out if this is a future, Its not one he wants to live in
