The Case of the Missing Marquess kicks off a (new to me) favorite series starring the much younger sister of Mycroft and Sherlock Holmes. (I blitzed through all six volumes of the Enola Holmes series in record time.) Beastly Bones is the second of the Jackaby novels, with another fantastical case. And Rowan Hood is the first in the 5-book series about the daughter of Robin Hood.
