The Wrath of Heaven

Seventeen years have passed since the battered refugees from Earth landed on the worlds of Scylla and Charybdis. They should have learned from their earlier mistakes. They should have remembered the remorseless artificial intelligence that now controlled the Earth, and its dwindling population. They should have remembered the resentment and hatred that entity bore for the last free remnants of the human race... but they didn't.
Now the populations of Scylla and Charybdis are about to pay for their mistake - with their lives.
Facing a distant and relentless enemy, sixteen year old Miranda Fatima Guitiérrez finds herself in a desperate fight for the world she has grown up on and loves and her very life. The Wrath of Heaven has fallen upon her.
