In six months, Ava's whole life fell apart, her parents died of typhoid fever, their house was sold to pay off debts... And now she and her brother are sitting in a hired carriage, taking them to the city where they left when Ava was only two of the year. The city of Wise is notable for one thing: it is the only settlement where magic still operates and people live in close proximity to the Outworld, the world of fairies. But the brother and sister discover that the magical city is rapidly losing its charm. By pure chance, Ava meets a fairy boy named Howell. It turns out that Ava and Howell are the keepers of a powerful magical artifact (the very Book that can predict the future). And the guys take up the investigation: after all, only they can find out why the magic that connects their worlds is decreasing.
