Clarissa is Marie Prevant’s psychic friend. Sometime before the events of the novel take place, she and Leon have a meaningful conversation about what Leon’s career in shipping means to him. Clarissa will eventually fall upon hard times and lose her house, forcing her to move into a van and live a transient lifestyle. The Prevants take inspiration from Clarissa when they decide to travel around the country in their RV after losing all their savings in Alkaitis’s Ponzi scheme.
