Larra's Diary is a tome found in Act II of Diablo III. It is found in Deserted Cellar and written by Larra, who gives it upon talking to her.
It is required for the Judge of Character achievement.
It reads as follows:
About a week has passed since the cultists found us. Mama told me to hide; I was always good at hiding. No one could ever find me because I would choose the places where no one wanted to look. Then they dragged my parents away... I can still hear them screaming.
