David, Christopher, April, and Jalil weren't the only ones swept away to Everworld. There is always the Other One. The one responsible for their presence in Everworld. Senna is on the fringe but also at the very center of the group. At last -- here is Senna's story.

Jalil and the others have made a big mistake. When they first met up with the Coo-Hatch, they agreed to trade April's chemistry book for some Coo-Hatch steel. Now the Coo-Hatch are using information from the textbook to create horrific new weapons. And they plan to use them to attack Mount Olympus.
