I didn't think it was possible, but I may in fact love this book even more than Gentleman's Guide. Felicity is the heroine that every single woman needs. Scrap that, she is the heroine that *everyone* needs.
Never once does she tip into a Mary-Sue; she knows her strengths and she manages her weaknesses, while being badass who keeps learning and growing!

The exploration of class, privilege and feminism intersect beautifully here, with characters being confronted by their own prejudices in a way that allows them to be examined and challenged. Girl gangs and intersectional feminism, hooray!!
