"Arthur Louis Pullman the Third . . . [has] been stripped of his college scholarship, is losing his grip on reality, and has been sent away to live with his aunt and uncle. It's there that Arthur discovers a journal written by his grandfather, the first Arthur Louis Pullman, an iconic Salinger-esque author who went missing the last week of his life and died hundreds of miles away from their family home. What happened in that week--and how much his actions were influenced by his Alzheimer's--remains a mystery. But now Arthur has his grandfather's journal--and a final sentence containing a train route and a destination. So Arthur embarks on a cross-country train ride to relive his grandfather's last week, guided only by the clues left behind in the dementia-fueled journal"--Provided by publisher.
