Reality and fantasy

Equandia blends real science with magical realism, and tells the reader with total clarity which is which.

This is real and verifiable

  • The natural phenomena: earthquakes, tsunamis, hurricanes, wildfires, droughts.
  • The safety measures and preparedness protocols that appear in the story.
  • All the science in the appendices, with sources you can look up.

This is fantasy

  • The Guardians' gift and Luna's ability to sense what is coming.
  • The five Primordials, ancient spirits of nature.
  • AMI, the backpack that conjures scientific instruments.
In the real world, no person or technology can predict an earthquake.
That is why each book includes educational appendices, a "fact vs. fiction" analysis chapter by chapter, hands-on activities and a teacher's guide.
Safety notice: the preparedness and response measures in this series are educational and do not replace official guidance. In a real emergency, always follow the civil protection authorities in your country.

Emblem of the Guardians About the author

Sol Andia

Sol Andia is the pen name behind Equandia. She writes for readers who ask hard questions: why the ground shakes, why the sea rises, what we can do before it happens. She believes a good story can teach more than a manual, and that no one is too young to learn to care for others and for themselves.
