About the book
Six strangers awaken in an isolated underground bunker with no memory of how they arrived or how long they have been there. Their only guidance comes from recorded instructions that claim they have been chosen to restart the human race. The world outside, they are told, has fallen. The bunker is their refuge. Their mission is survival.
But as the group uncovers fragments of their pasts and clues about the facility, they begin to suspect that the experiment is not what it seems. The truth beyond the sealed doors may be more dangerous than anything they imagine, and the secret at the heart of the trials forces them to question who they can trust.
With 4.2 stars on Amazon, strong Goodreads reception, and recognition as an Editors Pick for Best Science Fiction and Fantasy, this standalone thriller showcases A. G. Riddle at his most suspenseful.

While we live, the enemy shall fear us.

When Command assigns her brother to certain death and relegates her to Nursery to bear sons until she dies trying, she knows she must take humanity's revenge into her own hands.

About the book
They struck without warning. Now, survival depends on a man who’s never led.
Lieutenant Colonel Arthur Hanson was supposed to be an engineer, not a hero. Promoted to second-in-command aboard the CSV Margaret Thatcher, Arthur hoped for a quiet tour of duty—showing strength and keeping the peace.
He never expected a coordinated terrorist onslaught that would shatter the fleet and leave tens of thousands dead.
With the Thatcher crippled and reinforcements trapped behind political red tape, Arthur is thrust into command. Haunted by doubt but driven by duty, he must rally the broken survivors and strike back against a ruthless enemy who shows no mercy.
Because in the Orion Spur, freedom isn’t given. It’s fought for.
And aboard a ship named after the Iron Lady herself, surrender is not an option.
Perfect for fans of epic space battles, gritty heroes, and heart-pounding military science-fiction.
