by the end of Cities In Flight, Volume I;
by the end of Robert Heinlein's Future History, Volume IV;
before the beginning of Poul Anderson's World Without Stars;
before the beginning of Anderson's For Love And Glory.
Many sf characters have FTL without immortality and the characters in Anderson's The Boat Of A Million Years have immortality with STL.
There needs to be a very long novel or series about what immortality would be like over a very long period of time. As we count our age not in months but in years, immortals would come to count theirs in decades, then in centuries, then in millennia... Knowing that they had endless time in which to perform any given task, they might never get around to doing it.
Procastination is the thief of endless time? How else might their psychology change?
Addendum: John Amalfi briefly considers the psychological effects of longevity somewhere near the end of Cities In Flight but I can't find the passage right now.
