Matt Haig - A Biblioteca da Meia-Noite

On the threshold between life and death, after a life full of heartache and regret, Nora Seed finds herself in a library where the clock always strikes midnight and the shelves are overflowing with books that stretch as far as the eye can see. Each of these books offers you the chance to experience another life, to make new choices, to correct mistakes, to understand what would have happened if you had chosen a different path. The possibilities are endless, and various horizons open up before you.

But will any of these paths offer you a more perfect life than the one you've known? When it comes time for the final choice, Nora will have to look inside herself and decide what truly fulfills her life and what makes it worth living.
