What if you arrived home only to find it had changed beyond recognition?
Sketch leaves behind, Matt, Trevor, Jackie and her human family to return to the Core only to find it under the control of a tyrant. Isolated and without friends, she's powerless to change the world around her. Or is she?
Not knowing Sketch's peril, life continues for the humans, but a letter from the past will turn all their worlds upside down.
