Caldera (To The North)

This emotional, fast-paced sequel depicts the opening week of Yellowstone's catastrophic 2025 eruption, which sets into motion a gripping, intertwined survival adventure involving more than 10 different characters.

To The North began after the giant volcanic eruption had already taken place; Caldera depicts the days preceding and following this massive geological event. Caldera is a survival adventure and a dispersal drama. A natural cataclysm disperses our characters throughout the U.S. West in a fight for their lives; let's experience what happens to them.

Iraq vet and free-spirit survivalist Zeke Sanchez races his Harley through the Nevada desert on another loner vigil, until he decides to change course and rescue his daughter Tiva, who's a nurse in Idaho Falls, Idaho. During Zeke's journey, he runs afoul of noxious gases from the volcano, but also of a hornet's nest of predators who see societal collapse as an opportunity. Zeke realizes he must use his skills to protect his companions.

As soon as Yellowstone erupts, Kiatsu Garner bravely spirits her children along a benighted highway towards Oregon, in a race to save their lives. She derives strength from her father, Papa Saito, who has led a successful life in the U.S. after surviving the bombing of Nagasaki, as well as from the formidable internal resources she never knew she had.

Kiatsu's husband Brad desperately makes his way west from Chicago, in a fruitless attempt to locate and link up with his family, including the kids Jake and Abby.

The Yellowstone Volcano Observatory is manned by the scientists and researchers Slater, Monica, and Katy, who flee not only the lethal pyroclastic flows emanating from the erupting caldera, but their own clawing sense of guilt for failing to warn the region of the impending explosion (they had concluded that the volcano's recent activity represented a less profound hydrothermic event).

These protagonists' various journeys take them through Montana, Idaho, Nevada, New Mexico, and even down to Juarez where Aave, who Brad meets on the road, seeks to free a girlfriend from ransom-demanding kidnappers.
