Very interesting. I'd read the author's articles on slate.com about the Nobel Prize Sperm Bank and found them interesting, so when he wrote about his book I added it to my wish list. I never gave sperm banks much thought, so it was interesting reading about this particular twist on a world I knew nothing about. It was interesting to read about what happened to a few of the kids, and how they did when meeting the sperm donors, who were not Nobel Prize winners (no kids were born from the Nobel donors).
It was just... interesting.
