Schism is a novel in the Saga of the Skolian Empire, a series of science fiction books by Catherine Asaro.
Eldrinson Valdoria and his wife Roca Skolia live happily on his homeworld Lyshriol and have ten children.
Some of them have already left home, like the second oldest son Althor who is training to become a Jagernaut, or the firstborn Eldrin who at the request of the Skolian Assembly had to marry his aunt, the Ruby Pharaoh Dyhianna Selei.
The sixth of the Valdoria children, 16-year-old Sauscony (Soz), wants to enter the Military academy to become a Jagernaut like her brother.
The book is told from the perspective of several main characters – young Soz during her military training; Shannon searching for his lost kin, the mystic Blue Dale archers; and their father Eldrinson, being captured, crippled, and nearly tortured to death by a sadistic Aristo who infiltrated Lyshriol to destroy the Ruby Dynasty.
