Guardian Of Earth (Maggie Toussaint) Books in Order

Guardian of Earth is Maggie Toussaint's near-future science-fiction trilogy, published under her Rigel Carson pen name. The series takes place in 2065, when Earth is struggling with water shortages, disease, disrupted ecosystems, natural disasters, and uneasy governments. It treats those pressures as the background to a bigger mystery about who will protect the planet when the danger is hard to see.

Dr. Zeke Landry is at the center of the books. He is a water scientist, not a born action hero, and he would rather investigate a problem than stand before a crowd. But his uncle's disappearance pulls him into a dangerous search involving the Chameleons, a secretive group that believes Zeke possesses a valuable keystone.

Science is only the beginning of the problem.

Zeke's closest field partner is Forman, an advanced android whose skills make him valuable in a crisis. Forman can provide protection, data, and blunt practical advice, while Zeke brings scientific knowledge and an increasing willingness to act. Their partnership gives the series both its investigative engine and some welcome human, or almost-human, humor.

In G-1, Zeke follows the mystery around disappearing water and discovers that the Chameleons' interest in him is not accidental. G-2 brings apparent first contact when the Maleem arrive with offers of trade and cooperation. Zeke sees signs that the visitors are a threat, but the wider world is eager to accept their promises. In G-3, an unknown material left by meteor showers begins changing ocean water and endangering marine life, creating a crisis with consequences for everyone.

The series is interested in practical stakes. Clean water, food supplies, environmental collapse, public leadership, and scientific evidence are not side details. They are the reasons the threats matter. The futuristic technology, alien visitors, conspiracies, and android companion all serve a story that stays focused on Earth's vulnerable systems.

Readers should begin with G-1. Each novel has a complete central emergency, but Zeke's history, his importance to the Chameleons, and his relationship with Forman develop across all three books. The trilogy is a good match for readers who like science-fiction mysteries that keep their attention on the home planet rather than sending the action far into space.
