Rebel

In the early 21st century, an alien attack drove humanity to the brink of extinction. A thousand years after their defeat, the aliens haven't been seen since. Rada Pence has spent the last three years driving carts for an independent mining crew. Most likely, that's how she'll die, too. Then, deep beneath the ice of a Neptune moon, her crew discovers a long-lost ship. If it's from Earth's first space age, it would be worth millions. When they dig down to it, they discover it's not human - it's alien. And its secrets are worth killing for.
