The Call Of Earth by Orson Scott Card details from uread

Feeling itself to be failing, the Oversoul realises that it needs the technology of the Lost Earth to achieve its aims. It has already caused Nafai, a teenage boy, to commit murder ...

Nafai, his father and his brothers have left Basilica, but the rest of his family remain there, including his mother, the influential Lady Rasa. However, Rasa has other things on her mind, such as the 'friendly' invasion of troops under the leadership of General Vozmuzhalnoy Vozmozhno of Gorayni, who does not believe in any Gods, including the Oversoul - although he may still be its unknowing instrument.
