Is Ender's Game written in omniscient and what is a quote that proves it?

Yes, "Ender's Game" by Orson Scott Card is primarily written in limited third-person point of view. However, the narrator occasionally shifts to an omniscient perspective to provide insight into the thoughts and emotions of various characters. An example of this is when the narrator delves into the minds of Ender and his siblings to reveal their inner conflicts and motivations.
