A Final Stand

After finding the Atlas and helping the victims of PAMA rebuild, Jesse, Petra, Lukas, and Ivor reach their home world, with Harper accompanying them. They had expected to come back and find everything just as they left it, but a little further along. Instead, their journeys through the Portals took a little longer than they seemed, and nothing is the same. And not only that, but their travels have opened a rift in the Hallway, and unleashed a terrible power intent on destruction.

Can the travelers find their friends, Axel and Olivia?

Can they stop the strange power from corrupting the worlds?

And can one of the Order reveal his heart before it's too late?

Only time will tell.
