Stigmata Invicta

On a backwater planet in an otherwise barren solar system, an underground church thrives. For generations, the tyrannical world government has tried to stomp it out. But now, an elderly nun has brought hope to her suffering people when she begins experiencing a genuine stigmata. Her bishop requests her be rescued and taken far away. The Knights 15 13 send a spec ops team to do just that.

But these missions never go easily.

Discovered and assaulted from the land to the atmosphere, the Knights 15 13 rush to save the nun from the clutches of their enemy. An enemy who has much more sinister plans in mind. They don't want to just kill her. They want to force her to help them kill everyone.
