explores the story of Lee, a vibrant thirteen-year-old boy who is facing premature death from Progeria (a premature aging disease); his caretaker TomÁs, a survivor of Argentina's Dirty War, who is searching for his missing wife, who was pregnant when they were both "disappeared;" and Lee's single mother, Cass, overwhelmed by love for her son and the demands of her work as a Broadway makeup artist. When a mix-up prevents Cass from taking Lee on his "final wish" trip to Washington, D.C. and Philadelphia to pursue his interest in the life of Ben Franklin, TomÁs—who has discovered potential leads to his family in both cities—offers to accompany Lee on the trip. As one flees memories of death and the other hurtles inevitably toward it, they each share unsettling truths and find themselves transformed in the process. Set during the Ronald Reagan presidency, this lyrical novel transcends an adventure story to take the reader on an unforgettable journey.
