Enola Holmes meets Buffy the Vampire Slayer in this thrilling YA fantasy adventure!

Enola Holmes meets Buffy the Vampire Slayer in this thrilling YA fantasy adventure from debut author J. A. Morgenstein, perfect for fans of Jennifer Lynn Barnes and Philip Pullman.

It's 1909 and Rose Moriarty-teenage daughter of Sherlock Holmes' greatest enemy-has made a name for herself fighting monsters and solving crimes. But that was before Rose met the one mystery she couldn't solve- the disappearance of her headmistress. Now, her school has shut down, her classmates have scattered, and Rose is on her own.

On the very day Rose receives word that an old friend is dying, the shadowy Count Christoph and his ward Clara show up at her door. Rose has already figured out why they're here (to hire her) and what's in their bag (an ancient orb with incredible powers), but questions remain- Can Rose convince these strangers to help save her friend's life? What are the grotesque, bug-shaped stalkers that plague their every step? And how can Rose pursue this adventure while avoiding a certain boy from her childhood? The only thing certain is that Rose is no longer alone, because danger forges strange alliances . . .

. . . and Professor Moriarty wasn't the only famous villain to have a daughter.

Unexpected friendships, supernatural mystery, high-stakes heists, and budding romance billow together in this thrilling fantasy adventure, which introduces a motley crew of daredevil heroines who hunt monsters . . . in all their forms.

J.A. MORGENSTEIN has been a competitive ballroom dancer and instructor for the majority of his adult life, but during the lockdown, he found himself with the opportunity to focus his creative energy on his dream of becoming a writer. This started him down a winding road which culminated in The League of Dangerous Young Ladies. When not being bossed around by his pets, he enjoys dancing, British mysteries, and convincing himself that he can still eat the same things that he did when he was twenty-one.

Reviews for The League of Dangerous Young Ladies

""Snappy, charming, and hilarious, The League of Dangerous Young Ladies is a true romp that kept me turning pages way after my bedtime. I laughed a lot. Read this if you love a good found family, lots of banter, and fun twists."" -- Jodi Meadows, New York Times bestselling coauthor of My Lady Jane ""The plot is woven elegantly, the characters are rich and distinct, and savvy literary allusions abound, but the true pleasure of this novel lies in its fabulous narrative voice. Swashbuckling, spooky, and silly in equal measure, Morgenstein's writing is a dagger-sharp and delightfully cheeky celebration of storytelling."" -- William Ritter, New York Times bestselling author of the Jackaby series
