Griffeth, Bill (September 6, 2016). The Stranger in My Genes. Published by New England Historic Genealogical Society. ISBN 9780880823449.
From the publisher's book description: "Bill Griffeth, longtime genealogy buff, takes a DNA test that has an unexpected outcome: 'If the results were correct, it meant that the family tree I had spent years documenting was not my own.'"
This personal memoir by CNBC anchor Bill Griffeth was a short easy read on a topic that interests me in general as a genealogy and DNA researcher with my own (now solved) family mystery and because I share DNA with the author's Griffeth cousin. One small quibble is that the book confuses mtDNA with X-chromosomes (brothers with the same mother are expected to share identical mtDNA, not necessarily X-chromosomes, and mtDNA results for the author and his brother were almost certainly what he was comparing not X-chromosome data as stated). I therefore don't recommend it for the science aspect, but that represents a very small part of the memoir.
