Vinnie Holland, Mae’s father, is a loving parent who suffers from MS and is unable to get good healthcare. To help her father, Mae arranges for him to receive high-end healthcare from the Circle. However, Vinnie quickly becomes exasperated with the constant surveillance that the Circle demands in exchange for healthcare. As the novel goes on, Vinnie becomes an increasingly minor character, reflecting Mae’s alienation from her family and friends, and her growing commitment to the Circle’s mission.
