A nice bit of science reporting. However, the Author's almost giddy tone may be off-putting to some readers, particularly given the serious nature of the subject matter. Additionally, she falls a tad prey to overstating the case with regard to the science referenced. Also, some of the speculation, light though it is, reflects poorly. The quoting and commentary are relatively good and helpfully expository. The access to a large body of the referenced work is most welcome and for those interested enough to seek it out, well worth the effort. Aside from the aforementioned minor quibbles all in all a worthwhile and fascinating read. Three stars!
