Have you started the Flavia de Luce series yet?
So, so, so much fun! Clever and sad and funny and such a lovely little English world.
I have two major crushes in this series: Flavia herself and Dogger.
The Dead in Their Vaulted Arches is the sixth in the series and the best so far, for me. A cumulation of the larger mystery about Flavia's mother, the maturing of her relationships with her sisters, and Flavia poised at the edge of a new chapter in her life.
A couple of examples as to why this series is near and dear:
Upon being asked by another character to comfort her sister, Flavia thinks, "Well, a female shoulder was a female shoulder, there was no great mystery about that."
"Father was not a person who wore his heart on his sleeve. In fact, I sometimes used to wonder if he kept it anywhere about his person at all."
Dogger is such a fantastic character in his support of Flavia, and allowing her to kindness towards himself.
If you haven't yet started the series, you're lucky because now you've got six charming books in front of you!
