'The Sower", the Simon & Schuster logo, is perfect opening icon for this story about human seed sown by our common ancestors out of Africa and how you and I are related to the Jacobs clan. Like AJ's previous hilarious books, this one involves way-over-the-top performance art -- this time the mother of all family reunions, at which I sang "We are family" (and the rest of you 7.5 billion were expected to sing along). Genealogy is now, deservedly, tied for the top hobby, along with other ancient biotechnologies, gardening and sex. You could have no better guide than ace jovialist and awesome jester, AJ. Now, more than ever, we celebrate our connections, we read, we smile.'
