Bad Blood: Secrets and Lies in a Silicon Valley Startup

One of the best investigative pieces I've ever read - and also, by the nature of the case, horrifying.
This book deals with Theranos, the famous Silicon Valley unicorn (a term coined for a tech startup which is valued at more than $1 billion) and its neurotic founder, Elizabeth Holmes and her equally neurotic boyfriend, Sunny Balwani.
Many people have heard that Theranos has had shady dealings (myself included), but how shady they were is revealed by this book - a treatise on Theranos spanning from its foundation till its demise (of which the author was the main catalyst). The amount of laws and regulations that the startup flouted is staggering in itself. But what is more staggering is that the premise on which Theranos was founded (that hundreds of blood tests could be performed on a tincture of blood nipped from your index finger) and which gave Holmes a personal valuation in excess of $5.5 billion, was all a hoax. How this hoax came about, who all were wittingly (and unwittingly) involved in the hoax, and how the hoax could have led about to hundreds of deaths, forms the basis of the investigative novel.
On reading this book, one can easily understand how Carreyrou has won the Pulitzer Prize twice - his treatment is precise and cutting, and very easy to decipher and absorb - even medical laymen like me will have a ton to draw from the book, as is the book's intention.
TL;DR - roller-coaster work spanning the rise and fall of a Silicon Valley startup that got too ambitious for its own good, and in sight of its goal, flouted everything there was to flout. A dense but fulfilling read.
