The Forty-Year Passenger: A Novel of a Lost Brother, a Vanished Mother, and the Woman Who Has Been Mapping the Train Since 1981 (The Train Between Worlds Book 3)
Every door aboard costs the same thing to open: one true memory of the person you'd go back for.
Abel Quist has been on the train longer than almost anyone, and in fifteen years he has opened eleven doors. He spent the rest of that time mapping it — counting corridors, logging what he sees, carrying tea each morning to a brother who no longer knows they're related. Then he finds a surveyor's mark cut into a wall, dated 1981.
For: readers who want the map and the cost of making it.
