Strange things are happening at the small mining town of Coldstone. Miners have been disappearing and mysterious earthquakes are occurring more frequently.
When her twin sister and father are among the latest people who have vanished in the mines, Abby teams up with a young archaeologist named Sam, who has his own reasons for investigating the mysterious mountain. As the two head deeper underground, they end up finding more than what they bargained for...
This was another great story in the Heartland Storiesb - Series. In the beginning of the graphic novel the main character from 'Robocity', named Sophia and her little robot Max appeared briefly. This is the story of the twin sisters Abby and Ally who are very adventurious. But when Ally goes missing in the mines, Abby forms a duo with the young archeologist Sam to find her sibling. This graphic novel has the same style as 'Robocity' and I enjoyed it, along with the funny dialogues en the expressions of the characters. It got a bit creepy in the dark of the mines with the robits, but then there was Inion, a sort of robot made by the Mechanicians, that saved the day. It ended with a cliff hanger, so I hope the sequel will follow soon.
