Before you use a descriptive book to travel to another age you need to make a linking book in the overworld and take it with you, you use this to return.

OR if you didn't do that first, find a star fisure near where you spawned in the new age and jump in, not all ages have them, they look like a jagged short ravine with nothing in them, this may vary I've only ever seen one and was busy running at the time and didn't stop to take a SS.

OR cheat and spawn in a nether portal block and use this to goto the nether then leave the nether and you "should" return to your overworld, what you've called real world. The nether always links to your overworld, or is supposed to.
