Gertrude has been working tirelessly to finish The Tower as part of the bargain she made with Loki. The god has made no attempt to fulfill his end of the agreement, and Gertrude is out of patience as she waits to be reunited with her son.

When Ella uses Gypsy to travel back to Gertrude's timeline and make trouble, Gertrude is able to steal the ship to return to 2457 Fell. What she finds is a world in chaos with reoccurring shifts in time that thwart every attempt she makes to find her son and Kafir.

As Gertrude struggles through a world gone mad what she doesn't realize is that Ella is now pregnant, carrying a child who will bring about the end of Far Isle and every living thing in it. Gertrude's powers are tested in new ways and her son's abilities astonish all who encounter him. Will their combined power, aided by Gunnar, MacCuill, and the gods and goddesses be enough to combat this new evil? Or is it too late to save the world from ultimate darkness?
