This was a fun one that makes you think if you would make the same choice with its magical realism. After reading, I feel that the choices you make ..help you grow and learn and it's best to just leave things as they are. 

Mary the MC is having serious wisdom tooth pain. She is told by her cousin that if she gets them removed she will fall under the "Mulligan Curse" and go back to a time when she made a decision she might have regretted. 

Mary indeed gets to see where another choice would have led. But there are consequences that she didn't foresee and she might have to live with it.  It was nice to see her cousin guide her through this. I applaud Mary for making the first choice that she did because the other life was hard to imagine in her situation (you have to read to find out of course).
