A tedious examination of a totally implasible scenario resulting in the end of "life as we know it". Uninteresting characters spend endless pages discussing the philosophical and metaphysical reasons behind and implications of an occurrance that would certainly destroy the planet's current eco-system, but just could never happen. In addition, in the afterward, Pellegrino reiterates the urban legend regarding the death of Dr. Charles Drew, and claims it true. His poor fact checking further undermines any credibilty the science in this book may have ever had.
