Twice

Come to think of it, you do something wrong and can always go back and redo your past.

A bad grade on a physics examination? Go back and ace it. 

A wrong investment in today's stock market? Time travel to cancel the transaction.

A strikeout in a baseball game? Replay the game and hit the pitched ball.

A stupid choice in your driving route? Get a second chance and have do-overs.

That's exactly what happened in Mitch Albom's new novel Twice. At first glance, the power to relive any moment seems to be a gift. We don't have to take responsibility for the first mistake; we always get the second chance. 

Not endless chances, mind you. Alfie Logan, who discovered his magical power at the age of eight in Twice, learns to take advantage of the second chance. But it won't fix everything. He can't keep messing up and wiping the slate clean. He can only undo the first and get the second shot. Then, no more. The second time won't always be better than the first.  

And at some point, as Alfie finds out, we can get tired of reliving the past. If we count all the repeated hours, days, months, and years, Alfie Logan should have had many lifetimes. Which is why he said, "You're ready for what comes next."
