Grusha’s brother, who lives in the Northern mountains. Grusha travels to her brother’s house after fleeing Nuka, imagining that her brother will welcome her and her adopted son with open arms, giving them meals and a comfortable bed. When Grusha arrives, however, she finds that Lavrenti is married to a devoutly religious woman who both frowns upon fatherless children and fears that Grusha and Michael will infect her with scarlet fever or some other infectious disease. Thus, Grusha and Michael are forced to live in a dank basement, so that they are kept out of Aniko’s sight and out of her thoughts. Lavrenti eventually arranges for Grusha to marry a nearly-dead man named Jussup who lives in the nearby mountains in order to get her out of the house but still keep her safe and sheltered from the soldiers who are hunting her and her son. Lavrenti is a weak man, but not a corrupt one, and though his wife is judgmental, Lavrenti seems in his heart to accept Grusha and Michael.
