The Visitor

Evelyn Slater is launched into space in a Soyuz. It's claustrophobic, cramped, and she'd had to learn Russian to be part of the crew. Once on the ISS things would be different.
Her mission was to use the Scaffy Wagon to hunt down and destroy space debris. She was to be a glorified garbage collector.
Her third target is an ancient orbiting artefact* - and it hadn't been launched by any nation on Earth. What was it? Where had it come from? What was its purpose?
Governments were quick to slap TOP SECRET on it, but Evelyn had other ideas. Humankind's most amazing discovery deserved better than being buried in some secret military bunker.
The Visitor tells of Evelyn's attempts to enlighten the world, but will the world want to be enlightened?
