This is historic fiction at its best. The story of a intelligent young girl who hid her gender so that she could study in the monasteries. She rose in the Catholic hierarchy all the way to the top to become Pope - I guess she really leaned in to her career! People in Rome still talk about whether or not there was a female Pope and even today, one of the criteria before officially naming a Pope is for a Cardinal to check if he/she is male! I read this to prepare for a vacation to Rome. While we were there, Pope Benedict resigned the papacy which was the buzz the whole time we were there and made this book even more relevant.The audio version is beautifully performed by Barbara Rosenblat. This is one of those occasions of a perfect match between book and narrator - Bravo!
