Parallel

It's never too late to change,' (P.27 L.25)

I read Parallel, a level 1 book in the Cambridge English Readers. Max is main character in this book. He killed a woman at the station. He didn't feel well. One day, he met Fairhead and was told about parallel world. In the parallel world, he can see other him. I thought parallel world is interesting! People decide a lot of things by themselves and change their lives by choosing one thing.
It is important to decide by myself. I don't want to regret my choice. If there is parallel world, I want to go there.
Do you want to go there?
