The fate of Earth-and one man’s heart-hang by a thread.
For the first time in twenty-five years, Earth has sent a signal to the Interstellar Space Coalition (ISC). Captain Tim Spalling - grandson of the legendary Renn Spalling (from Guardians of Earth I & II) - travels to Earth to discover why. It is a mission he never wanted and fears he can’t control. The weight of his family’s legacy looms large, eroding his confidence at every turn. But when the team arrives, the truth is worse than he imagined: the northern hemisphere is nothing but ash, and of Earth’s 8 billion people, only 200,000 remain, struggling to survive in the radiation-choked south. Every decision Tim makes could mean life or death-and every failure could destroy humanity’s last chance for survival.
Now stranded on Earth, Tim faces an impossible task: eliminating the radiation killing the survivors and his advanced android team. But as a malevolent alien force lurks in the shadows, Tim’s growing connection with an Earth woman begins to cloud his judgment-and threaten the mission.
With time running out and enemies closing in, Tim must confront his greatest challenge yet: how far is he willing to go to save a dying world and those he cares about?
Tense, action-packed, and emotionally charged, The Emissary is the latest gripping installment in the Guardians of Earth saga.
