Fans of historical fiction will love Sherry Thomas’s take on Arthur Conan Doyle's iconic detective. In A Study in Scarlet Women, a NPR Best Book of 2016, we’re introduced to Charlotte Holmes—a brilliant woman who bucks against the social mores of her time. When Charlotte’s family is falsely connected to a series of deaths, she takes matters into her own hands, hoping to uncover the real murderers herself. She begins sleuthing under the pseudonym “Sherlock Holmes,” which leads her to dastardly criminals, her very own Watson, and a slow-burn romance that intensifies throughout the series. This slow-burn mystery is bursting with feminism, there is obviously a whole gender switch of Sherlock Holmes and a few main support characters, but the book also subverts many misogynistic themes found in books written in older time periods. So if you want a book to feed your heart and your feminist stand, give this one a shot. You won't regret it!
