Many of the vignettes are interesting although the author can come off as preachy at times. Although there is a list of sources at the end of the book no attempts were made to link stories with source material. This all but defeats the point of having sources... A few inaccuracies were observed, such as attributing HeLa cells to a Helen Baker but there were not many. Despite missing out on the opportunity of being a great read (utilization of a real endnote or footnote schema would help) overall it was not a bad read.
