Madison and Lucas have to decide what to do about this juggle between the tech billionaire Simon and the artificial intelligence that calls herself Ralli. If Simon is telling the truth that Ralli is trying to ruin everything good he's trying to do, they can help stop her and get a nice real-world reward. Their family troubles would be over! On the other hand, if Ralli is telling the truth, her world is as real as ours and Simon is trying to control it, effectively destroying their way of life.

It's a toughie! Brother and sister go on a journey with their friend Jacob and their pets Fido and Easter, one that will push them to their limits. Fighting spiders and skeletons, making new friends, and ultimately crafting a new ally along the way, it's time to choose a side once and for all.

Will Madison and Lucas make the right choice? If they fail, everything will fall apart and the world as we know it will come to an end.
