In 2026, they killed off 85% of mankind. In 2042, we finally beat them because of a resistance borne of one man. But in 2045, gorgons don't give up easily - and now they want revenge. === After 16 years of alien invasion, the resistance annihilated the gorgons, deposed President Jean Graham, destroyed the gorgon queen, and leveled the funnel, which was stealing our water. But the victory was short-lived. A second craft now approaches, trying to re-establish communication with its predecessor. Earth's survivors have only just been reemerging out of the shadows for a desperate three years. The horrible truth is confirmed: the enemy is coming for them once more. And now the gorgons know precisely who led the revolt: none other than President Vance Cardona himself. The time for the gorgons' revenge has come. Will this be the end of all humanity? Not if the President and a few brave, stout souls have anything to say about it. === Volume IV: Relentless is the final installment in Aaron Ryan’s epic science fiction alien invasion series. Experience true tension where the stakes are high and terror lurks around every corner! "An inspiring novel of unflinching resilience and resistance in the face of overwhelming odds. Ryan isn't afraid to dive into the weeds of military procedures, which makes the novel immediately immersive, as if these events really happened. The dialogue is crisp and the characters are deeply developed, with believable relationships and complex dynamics of national duty, emotional commitment, and personal loss. Extending a captivating story arc now entering its twentieth year, this novel offers a riveting escape into a fractured but hopeful future." -Self-Publishing Review ★★★★½ "Through the smoke and thunder of humanity's second stand against extinction, Aaron Ryan's "Dissonance Vol IV: Relentless" soars with raw intensity and heart-wrenching emotion. Like a DTF blast piercing the dawn, this finale to the Dissonance saga illuminates both the savage nature of survival and the unquenchable light of human spirit. Ryan's prose carries us through firefights and presidential decisions with equal grace. The climactic battle for Washington DC unfolds like a symphony of chaos - fighters diving through alien mists, snipers calling targets through smoke, while deep below ground something ancient and terrible stirs. Yet in these moments of supreme violence, humanity's finest qualities shine brightest: sacrifice, unity, and relentless determination to survive." - The Bookish Elf This is, hands down, the most powerful story I've ever been able to tell. I'm immeasurably proud of it, and grateful to have been privileged to author it. I hope you are whisked away by it and taken on a dizzying and incredible journey. Thank you for your support!
