The Inventor: Out for Blood in Silicon Valley ★★★½

The one thing all the Theranos books/docs/articles are missing is a sense of Elizabeth Holmes as a person. She's completely opaque, and all the coverage of her suffers as a consequence. This is no different. Either no one who knows her is willing to talk, or she never let anyone see beyond the facade. The facts surrounding the fraud are interesting, but the mystery surrounding her motivations makes this a mildly frustrating experience.
