The Midnight Library

Between life and death there is a library. 

When Nora Seed finds herself in the Midnight Library, she
has a chance to make things right. Up until now, her life has been full of
misery and regret. She feels she has let everyone down, including herself. But
things are about to change.

The books in the Midnight Library enable Nora to live as if
she had done things differently. With the help of an old friend, she can now
undo every one of her regrets as she tries to work out her perfect life. 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:
what is the best way to live?
