No, (to respond to other reviewers), I can see how you can say that this really isn't a children's book, esp. after the devastating epilogue. But the author knows that one should not talk down to children, and knows that many are capable of handling heavy, provocative material. It's a little dated, as near-future SF can't help become, but if you can still find value in the books "1984" and "2001" you can find value here.
Explorations of the Holocaust, of cloning, of eugenics, of musical or mathematical genius, of scientific hubris, of overpopulation, all work together to encourage the reader, age 10 up, to think about themes of identity, community, family, and the difference between intelligence and wisdom.
I make it sound earnest, even preachy, but it's not. It reads like an adventure combined with a coming-of-age story. I recommend it, if you can find it (my copy came from a university library) and I will look for more by the author.
Off to Google for Reverie by Clara Muller and Love Story by Mancini. (The former may be invented for the story.)
Oscar Wilde is quoted:
“After playing Chopin, I feel as if I had been weeping over sins that I had never committed, and mourning over tragedies that were not my own. Music always seems to me to produce that effect. It creates for one a past of which one has been ignorant, and fills one with a sense of sorrows that have been hidden from one’s tears.”
Author says, through Anna's dad, "Tchaikovsky, Chopin, and Mendelssohn never turned out anything with substance. They were shallow men. Beethoven now--he storms, he raves, he growls. He takes us to the depths of hell and lifts us to the skies."
