Earth’s Last Stand: Sentinel Five The Krylok Swarm has arrived—and Earth is on the clock. From the void came fire, silence, and annihilation. Alien warships darken the skies, cities burn and buried in the planet’s core lies their ultimate weapon: a bomb designed to shatter Earth itself. Humanity has only thirty-six hours left. Hope rests with Sentinel Five—an elite squad drawn from the world’s deadliest warriors: Commander Jack Ross – calm, ruthless strategist. Captain Li Wei – urban combat perfectionist. Major Nikolai Volkov – scarred Spetsnaz giant. Lieutenant Elena Alvarez – cyberwarfare mastermind. Lieutenant Mark O’Connor – daring pilot and sharpshooter. And at their side, something beyond human: RAID (Rapid Assault Intelligent Destroyer)—half man, half machine, built to strike with impossible speed and devastating power. Together, they must tear through alien swarms, destroy the spires, and confront the alien warlord Sprok, a towering commander whose strength and brutality have broken entire worlds. The mission is clear. The clock is ticking. Failure means extinction.

Pleased to have launched my first sci-fi book, Earth's Last Stand: Sentinel Five. 🚀
If you enjoy high-stakes action and interstellar mystery, I’d love for you to read it. Linktr.ee/guyhee
