This book was an interesting read but at some times it was rather repetitive. That seemed to be a result of the repetitive events that took place more than the writing, but it did lend the book to become dull at some points. Overall, it was extremely interesting. The rise and fall of Theranos (which is still happening in multiple courts in multiple states at this time) was an unbelievable ride. The young owner managed to scam and mislead people to a multi-billion dollar company which produced no legitimate results whatsoever. Seeing how she managed to mislead and charm people with decades of experience in multiple fields while having none of her own, was astounding.
