WITHOUT A DOUBT by Surbhi Sarna is a new business book intended to describe "How to Go from Underrated to Unbeatable." Sarna is an entrepreneur and partner at Y Combinator, a technology startup accelerator. She frankly shares her own medical journey, beginning at age thirteen when she was diagnosed with a potentially cancerous complex ovarian cyst, saying "I was angry. We'd had to do too much guessing and waiting. We were forced to make so many impossible choices." That experience (and her innate interest in science) led Sarna to eventually form a company that developed, tested, and patented a process for earlier, more accurate detection. In the text, she reflects on "the weight of doubt pulling at us while we try to reach out goals" and encourages her readers to realize that "your power lies in recognizing the qualities that make you different and leveraging them to pursue your dreams." The content is accessible, motivating, and exciting – even with setbacks as she admits, "I'd stumbled again and again, sometimes barely making it back onto my feet" before selling her business to Boston Scientific for $275 million and going on to advocate for other young entrepreneurs. WITHOUT A DOUBT received a starred review from Kirkus and was named one of "40 Nonfiction Books to Watch Out for in 2023" by The Next Big Idea Club which also highlighted other non-fiction titles available on NetGalley like Unraveling (a personal favorite!); The Climate Book; The Big Myth; Four Battlegrounds; The Teachers; and The Real Work.
