Nadia Zhabin is a Squaller who resides at the Little Palace. She is friends with Marie and has a younger brother, Adrik.
Shadow and Bone
Nadia and Marie befriend Alina Starkov soon after her arrival at the Little Palace, accepting the newcomer into their little group. Like Marie, Nadia dislikes Zoya, though she acts as though they were friends.
Siege and Storm
Nadia is one of the few Grisha who decides to stay at the Little Palace after the Darkling's attempted coup and the growing tension between the First and Second Army. With Marie and Sergei now a couple, she is often left behind.
When Alina evacuates the Grisha children from the Little Palace, Nadia petitions her to let her brother, Adrik, stay and fight despite his age. She and Adrik are among the few to survive the Darkling's attack on Os Alta, and they follow Alina to the White Cathedral.
