Shadow Puppets (Ender, Book 7) (Shadow Saga)

how many millions of humans have already been born and died as loose threads with their lives snipped off?

"My boy, you are so noble!" Anton let go of him, taughing. "Listen to yourself! So full of the romance of youth! You will save the world!"
    "I didn't mock your dream," said Bean.
    "But I'm not mocking you!" cried Anton. "I celebrate you! Because you are, in a way, a small way, my son. Or at least my nephew. And look at you! Living a life entirely for others!"
    "I'm completely selfish!" cried Bean in protest.
