Along with transforming my previous image of Miss Gwen from a Nanny McPhee-looking harridan to Catherine Zeta-Jones with her hair pinned up, The Passion of The Purple Plumeria is the best of the last several books in this series. It's a definite return to form, and its ending makes me want to see The Pink Carnation go dark. I adore the light, fun, romantic, and slightly silly tone of this series but I absolutely must see Miss Jane Wooliston get in too deep and go full Bourne (or as realistically Bourne-adjacent as possible for a woman in 1800s England). I want steamy verboten enemy spy romance that breaks her careful facade and sends her into reckless rogue territory. That may be exactly what just happened here. I don't know. I just know that I desperately want more of it.
