Step-by-step explanation:

Novinha loses both her parents and later her husband and children, while Ender loses his older sister and his entire family is separated from him. Additionally, both Novinha and Ender are thrust into positions of responsibility at a young age, with Novinha becoming a xenobiologist and Ender being chosen to lead the International Fleet.
