The Immortalists by Chloe Benjamin
From Penguin Random House:
If you knew the date of your death, how would you live your life?
It’s 1969 in New York City’s Lower East Side, and word has spread of the arrival of a mystical woman, a traveling psychic who claims to be able to tell anyone the day they will die. The Gold children—four adolescents on the cusp of self-awareness—sneak out to hear their fortunes.
The prophecies inform their next five decades. Golden-boy Simon escapes to the West Coast, searching for love in ’80s San Francisco; dreamy Klara becomes a Las Vegas magician, obsessed with blurring reality and fantasy; eldest son Daniel seeks security as an army doctor post-9/11; and bookish Varya throws herself into longevity research, where she tests the boundary between science and immortality.
A sweeping novel of remarkable ambition and depth, The Immortalists probes the line between destiny and choice, reality and illusion, this world and the next. It is a deeply moving testament to the power of story, the nature of belief, and the unrelenting pull of familial bonds.
