We all have regrets-choices we could have made differently, oaths we didn't take, other live we might've led. But what if you were given a chance to fix your past? Enter The Midnight Library.

Nora's life has been going from bad to worse. Then at the stroke of midnight on her last day on earth, she finds herself transported to The Midnight Library, where each book contains an alternate life: a possible world in which she made different choices. She is given what seems like the ultimate opportunity: a chance to undo her regrets and try out of the other lives she might have lived. But things aren't always what she imagined they'd be, and soon her choices place the library and herself in extreme danger.

Before time runs out, she must answer the ultimate question: With infinite choices, what is the best way to live?
