Em and Matt Calder are back to save the world. You thought after defeating Tanan and the Hollow Earth Society once that it would be all good, case closed? Ha! You thought wrong! After the incident that ripped through the family, Matt and Em are stuck in a world without animating, which at the moment, meant no drawing, making art, or coloring of any kind until they could get their powers under control. But do you think that will stop them? Of course not, because in a book, do main characters usually do what their told what to do? So in a trip to 19th Century London, Zach is separated from Matt and Em, so Matt and Em use water skis to chase after him, accidently scaring some fisherman, and Zach almost gets killed. Typical time-travel. When the group comes back, all the adults are angry. Except Sandie. Did I mention she disappeared? Oh, and a book filled with monsters is close to being unleased, which would overrun the world with monsters. So, the sum up the situation, it’s pretty bad. The second book in the Hollow Earth series will sure to keep you on edge.
