The Inherited Starship. Starship Legacy, #1

A First Contact Space Opera. He was supposed to finish his shift. Instead, he inherited a war. Adrian Mercer has spent his life repairing industrial machinery, not chasing impossible dreams. Then an ancient object crashes behind the factory where he works-a silent starship older than human civilization. The moment Adrian touches it, everything changes. The vessel recognizes him as its captain. Across the galaxy, powerful empires, ruthless mercenaries, and forgotten civilizations awaken to a signal that should never have returned.
They all want the same prize: the mysterious Legacy Ship now under Adrian's command. Buried within Herald's damaged memories lies a secret left behind by the First Architects-a secret capable of reshaping the balance of power across the galaxy. With no military training, no allies he can fully trust, and no way back to the life he left behind, Adrian must learn to command a sentient starship unlike anything the modern galaxy has ever seen. Every hyperspace jump uncovers new enemies.
Every discovery reveals a deeper conspiracy. And every victory brings humanity one step closer to an ancient war it never knew existed. Perfect for readers who enjoy cinematic space opera, first contact adventures, sentient starships, ancient alien mysteries, reluctant heroes, found family, and galaxy-spanning exploration.
