When Earth is at it's quietest, the population unsuspecting, the planet is in imminent danger. An advanced human race lands on Earth in an attempt to take over.

But when the group is struck to the core by something unexpected, it becomes even harder to do so.
Will they successfully overthrow them? What losses will they meet in their attempt?
But most importantly, will they survive through the terrible siege?
