ARC Angel


Toby Neighbors - 2018
    Ravenous, insatiable, and completely merciless — in decades of space exploration and expansion, nothing like the Swarm has ever been encountered. They swept across the colony world of Cannis One, devouring every resource. Humans, working to build a new outpost on the small world hidden in the binary star system Sirius, were helpless to stop them. Even with the help of the Colonial Space Fleet, every effort to destroy the aliens has failed. Angela Murphy has spent the last decade training to make the National Gymnastics Team. She has the skill, the passion, and the dedication to be an olympic athlete, but she’s outgrown the preferred body shape of most gymnastic competitors. Still, she won’t give up on her dreams, not when there’s still a chance that she could find success. Staff Sergeant Jonathan Cashman leads a fire team of highly skilled Marines in the Colonial Space Fleet. Stationed on Mars, they are ready to face any threat at a moment’s notice. Yet inexplicable orders have them returning to Earth for a top secret assignment at the CSF Research & Development testing grounds. ARC - Assisted Rapid Combat is a breakthrough in military technology, making the extraordinary possible, and forging the ultimate weapon against the Swarm. But it will take the right kind of soldier to become a weapon and prove that the ARC suit can make a difference in the war for Earth’s colonies. Time is running out, and so are humanity’s options for survival. ARC Angel is the latest Military Space Opera from prolific author Toby Neighbors.
