Springer (Rowan Hood
; I Am Mordred
) proves that she is as comfortable in England's late 19th century as she was in Sherwood Forest and Camelot with this debut title in the Enola Holmes Mystery series. Her heroine, however, is not. After Enola's mother disappears, her older brother, Sherlock (yes, that one), and oldest brother, Mycroft, whom she has not seen in 10 years, seem bent on forcing her into a steel-ribbed corset and sending her off to boarding school. But Enola ("which, backwards, spells 'alone
,' " she points out) rebels. Her mother has left behind a little book of ciphers, so the 14-year-old disguises herself and heads to London, where she hopes to outwit her brothers and find her mother. Readers will find the teen's internal monologue quite entertaining ("Always I felt to blame for—for whatever, for breathing—because I had been born indecently late in Mother's life... And always I had counted upon setting things right after I was grown.... So she had to be alive"). Along the way, Enola becomes involved in the search for the missing Viscount Tewksbury, Marquess of Basilwether, and hair-raising adventures ensue. Enola shows herself to be an intelligent, rational, resourceful and brave protagonist. Readers will look forward to hearing this heroine's unique voice again soon. Ages 9-up. (Feb.)
