SPSFC

An ancient threat returns to conquer humanity. They ruled the planet once and they will do it again. Humans can't fight this war—not without help. For years, Dr. Ethan Fawkes has been communicating with a mysterious scientist using an encoded signal, and together, they designed the first spaceship meant for war. But when the government orders Ethan to dismantle it, his collaborator reveals a terrible secret. An army of powerful aliens is about to invade Earth, and humans must rush to prepare a defense or risk losing their freedom forever. Collaboration with an unlikely ally is humanity’s only chance at survival. Fiona has no memories of her origins, but somehow, she shares half her DNA with the invaders. For this, she lives a life of scorn and shame amongst humans. When the enemy arrives to enslave her village, will she help the humans who hate her or join the aliens who welcome her? The key to victory lies in the depths of her obscure past. Can she remember her true heritage before it's too late? The Lost Signal is the first book in the Slaves of Zisaida trilogy: a riveting Science Fantasy saga about our galaxy's war for survival against an intergalactic threat. If you're a fan of Stargate, The Atlantis Gene, and Battlestar Galactica, get on this thrill ride. Come for the Space Force, stay for the aliens.
