“Oath of the Family” is another novel about post-indigo Scorpio. Together with his named brother Sema, Scorpio continues to comprehend the structure of the universe, the origin of the forces of good and evil. Great ancestors - gods and demigods - help in this knowledge, but still the main strength of the children lies in themselves. Rushing to fight the forces of evil wherever it is required, they more than once find themselves on the brink of death, and only superpowers help them survive and win... But the enemy plays on the most vulnerable: love, a sense of duty and a sense of brotherhood can disarm, just as they will not disarm no sword.
