Shadow and BoneEdit
Adrik is among the children studying at the Little Palace's school for young Grisha.
Siege and StormEdit
When Alina Starkov evacuates the Grisha children from Os Alta, Adrik insists to stay, claiming that he's old enough to fight. Nadia agrees, saying that she doesn't want to be parted from her brother. Alina replies that it would be even more difficult to bury him, though she eventually agrees.
Adrik is among the Grisha present at the Little Palace when the Darkling attacks the Little Palace. He is among the few to survive the battle and follows Alina to the White Cathedral.
