Between life and death there is a library, and within that library, the shelves go on forever. Every book provides a chance to try another life you could have lived, to see how things would be if you had made other choices. Would you have done anything different, if you had the chance to undo your regrets? Up until now Nora Seed's life has been full of misery. When she finds herself in the Midnight Library, she can now undo every decision she regrets. But things aren't always what she imagined they'd be.
