Of course, this legacy is not without its costs: There are those who will give anything to find a way in. With the help of her father, a mysterious stranger named Alex, and some unexpected heroes, Evie must guard the storeroom against ancient and malicious forces, and protect both the past and the future even as the present unravels.

At stake is the fate of the world and the prevention of nothing less than the apocalypse.
