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 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 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.

YOU GUYS ARE NOT READY FOR THE LEAGUE OF DANGEROUS YOUNG LADIES! Enola Holmes meets Lockwood & Co in this smart, snappy, and fast-paced adventure series. The TWISTS! The NODS! The text never dumbs anything down for the reader, or tries to explain the references it makes, and respects the reader enough to let them either get it, or figure it out. This is a book I would've been obsessed with as a kid (heck, I'm obsessed with it now), and I can't wait to see where these characters go.

Review of advance copy received from Edelweiss+

Thank you to Edelweiss for the ARC. I didn't feel that this story was giving anything new. Non of the characters are truly likable and therefore one can't fully become invested in them. The plot and mystery was weak and did not keep my attention despite hoping it would give more as it went, but unfortunately it failed to deliver. I also think the teensof today might have a hard time grasping all the nuance references that are too heavily used.

I thoroughly enjoyed my time with League of Dangerous Young Ladies. It is full of adventure and twists, but also heart and found family. There is a depth to these characters and many touching moments, along with a witty humor.
This book appeals to readers of all ages. Though it works as a stand alone, I look forward to more adventures with these characters.
