The Long Dark

Trapped in the lengthening nights of Elysium. Abandoned by the last convoy south. Alone with her teenage son. Anna never thought she would die this way. It won't come to that. She won't let it. She scours the darkened town for anything to help them make the long trek to rejoin their clan. But on a world starved of engineering resources it will take all her ingenuity to cobble together a usable vehicle.
A chance of escape is almost in reach when Anna finds they are not as alone as she thought. But the unexpected visitors are on a mission that they will kill to keep secret. Whatever these off-world intruders want, it can't be good for Anna's world, and a fight to save herself and her son becomes a battle for the future of the entire colony.
