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.
The League of Extraordinary Gentlemen gets a feminist makeover in this new YA book from first-time author J.A. Morgenstein.
Rose Moriarty, daughter of Sherlock Holmes' nemesis James Moriarty, leads a pack of exceptional young ladies including scientist Nikki Tesla and Dr. Moreau's daughter Sefina. They team up with Count Dracula and one of Frankenstein's creations to help find a cure for Nikki's irradiated blood, a condition she picked up from her time with Marie Curie.
This book is romance-light, with a flirtation between Count Dracula and Nikki Tesla, and Rose's budding relationship with Dr. Watson's son Jim.
The novel ends with several twists that will leave readers wanting to know what happens in the sequel. There are also hints of other famous daughters that will make an appearance in the next installment. Recommended for readers of YA fantasy or historical fiction.
I received an electronic ARC of this title from NetGalley in exchange for an honest review.
I enjoyed this book far more than I expected. What do you get when you bring together characters from classic novels, but not exactly in the way you'd expect?
The league of dangerous young ladies, that's who.
The storytelling could be a bit tight in some places and some of it is a bit more tell than show for my liking. But overall, a pretty enjoyable read.
I received an advanced copy from the publisher. The blurb on the back said this was a mix of Enola Holmes and Buffy the Vampire Slayer, which was spot on in my opinion. This was a fun read with lots of literary and historical references. It also had some good twists in the end.
Thank you so much to NetGalley for the ARC! This is an utterly charming, humorous, and heartfelt romp with the daughters of some of history’s and literature’s most infamous names. While action-packed with a plot that keeps one guessing, it’s the consistent theme of sisterhood and found family that really makes the work shine.
Dangerous young ladies. Extraordinary young ladies. Bad-ass young ladies. I’ll let you decide after you finish reading this witty, humorous, amazingly fun read by J. A. Morgenstein.
Let’s start with the cast of characters. At first, you’d think that the daughters of Frankenstein, Professor Moriarty, Professor Moreau, and Nikki Tesla (which I think is a play on the inventor Nikola Tesla) would be out doing villain-type things, but they are actually working together to stop a superpower from falling into an ancient villain’s um…pincher’s?.
Now, let’s get into some of the core details. This book gives me Apprentice to the Villain vibes. However, this is very much a YA novel, so expect teenage emotions to sit right alongside high-stakes conflict. This is told from the prospective of mostly teenagers from multiple points of view, and while that adds variety, it also makes things harder to track at times.
The dialogue is witty, the fight scenes are consistent, and there is even some shape shifting, and love sprinkled throughout. I could easily picture some of these moments playing out like a cartoon detective movie. That said, the multi-narration does not always work in the book’s favor. Scenes move quickly, perspectives shift often, and sometimes the story feels like it is jumping ahead before moments have time to fully land. I also found parts of the book repetitive, especially with Rose, whom I would call the main character. Her struggle with the loss of her headmistress is meaningful, but it circles the same emotional beats often enough that it starts to lose impact and you kinda want her to deal with it or get over it. Still, I appreciated how the author wove in life lessons and highlighted qualities that point toward growth and accountability.
There were several things I really enjoyed. The diversity of the cast of characters is exceptionally well done, even if they were the author’s interpretation. There are bugs, shape shifters, vampires, and monsters which is everything I love about fantasy novels. Even though parts of the storyline feel underdeveloped because of how quickly scenes change, there are plenty of nods that add extra context and depth. Those small details made the reading experience more engaging. The unexpected twists also helped keep the momentum going and made it easy to keep turning the page. Even the cast of characters had me wanting to go back to revisit some old Sherlock Holmes books.
For the author’s first novel, this is a strong start. The book is creative, fast-paced, and clearly setting up something bigger. If you enjoy YA stories with a large cast, sharp dialogue, and a twist on classic villain origins and fantasy, this is one you will want on your to-read list.
Thank you to the author and Sourcebooks for the ARC.

💬 Which literary villain would you want to see get their own next generation story?
Echoes of Sherlock Holmes meets monsters, adventure, and fantasy from other tales and myths, mixing with a group of unexpected friends in an entertaining and suspenseful way.
Count Christoph has gotten his hands on the sphere, an object said to grant god-like powers, but it's very unclear how it works. Luckily, his assistant, Clara, knows where to go and leads him to Rose, the daughter of Professor Moriarty. Her cleverness is unparalleled, but she has her own issues as she's in a race to save a former teacher, an amazing genius in the science realm who suffers from an incurable disease. While Rose agrees to help the Count for a favor only he can give, solving the sphere is just the beginning of that task, since dangerous bug-men are determined to have the sphere for themselves and will do anything to get it. But Rose isn't alone, and her friends are nothing to scoff at. But then, the Count and Clara hold more than a few small secrets, too.
This is a fun read with tons of spunk, character quirks, scenes to keep the reader on the edge of their seats, surprises, and even humor. It's historical setting places it around the late 1800's/early 1900's-ish. At least, there is the mention of very rare cars, while carriages still seem to be popular. It flies all over the world as the clues lead the odd group from one unexpected situation to the next. It's impossible to guess what is really going to happen on the mystery end, but then, this entire world is unpredictable. After all, you have the ancestors of Holmes and Moriarty involved, nods toward vampires, Frankenstein, and echoes reminding of The Umbrella Academy. It's fast-paced, brings action, and keeps secrets flowing with every page.
While imagination abounds, the characters bring quite a bit of personality to spice things up even more. Each one shines in their own way, making the group a broad mix in so many respects. This leads to fun interactions and adds unexpected moments as well as ones to smile. But it's not all fun and games as each one also carries a mighty amount of luggage from their past. Some characters have worked through their issues already, while others like Rose have more than a little inner-conflict to still sort out. There are also friendship struggles and trust hurdles between the newly forming friends, which melds between the other moments to add heart and give the reader a second to take a breath before dashing into the next impossible situation.
It's a quick-paced read with plenty of energy and spirit...and it will be a treat to see where another adventure might lead this league of individuals next.
Thank you to NetGalley and the publisher for the chance to review this ARC. Unfortunately, I did choose to DNF this book at around the 25% mark, trying to give it the fairest chance that I could while getting to know the characters and the world.
I do 100% want to start with the clarification that a part of this choice is that the YA genre spans a vast spectrum, and, for me, this didn’t feel like the right fit age-wise.
There is a huge amount of potential, and for the right reader, I think this could be a really engaging, fun, and charming read. The story essentially follows Moriarty’s daughter on a supernatural mystery adventure. The description highlights the fact that it is a bit of Enola Holmes meets Buffy the Vampire Slayer, which absolutely comes across. There are definitely elements of the writing, in particular very inspired transitions between chapters, that showed a strong instinct for hooks and tone shifts that alone might cause me to pick this up in the future for inspiration.
However, there were a lot of things that pulled me out of the story. There are a lot of exposition dumps and over-explaining. The dialogue and actions do a lot of heavy lifting on their own, only for the narration to restate or label the same emotions or traits. This might be appropriate for a younger audience, but it really pulled me out of the story and really began to blunt the impact of otherwise witty and smart moments.
I don’t actually want to be too critical here, because again, I think the major flaw is that I am just not the audience for this book. Some of the things that bothered me would be very effective at a middle-grade or slightly older level, like the overcompetence and resources of these very young characters. I had a difficult time suspending my belief that a sixteen-year-old has been engaged with supernatural phenomena for at least three years, but I do remember being younger and writing very similar situations myself and feeling like they were completely realistic.
One really fun aspect of this story was the way that literary legacies and historical figures were represented and referenced. I did have some nitpicking here, but as I did not complete the book, I don't want to mislead anyone. (On a positive note, I am shamelessly a little gay for Nikki Tesla).
I’m going to give this three stars because I do believe this would make a great read for a different person, and I do wish I were able to look past some of the things that irked me to continue.
Although I mostly read YA, The League of Dangerous Young Ladies surprised me, both in good and bad ways. Let’s start with the bad: this book reads young, which is a bummer because the book’s premise is promising.
This book focuses on the descendants of iconic book characters, some of whom make an appearance. Mentions of Sherlock Holmes and Irene Adler aren’t new in a mystery, but in this novel, the appearances don’t overshadow the vibrant main character. That’s a feat on its own. Meet Rose Moriarty, a young girl navigating the world of a mostly men-run world of detectives. Not only is she a young woman, but she’s also Jim Moriarity’s daughter, a person embroiled in the mysterious death of Sherlock Holmes.
Narratively, the novel is layered. There are several mysteries to solve at a time. You won’t be bored reading The League of Dangerous Young Ladies. Even if the plot slows down in certain places, the fight scenes are energized and lively.
Speaking of fight scenes, I have to mention how emotionally developed the characters are. Rose stood out as a character of her own, rather than the “daughter of Moriarty.” She is met with so much doubt from her client. Rather than lead the investigation independently, she has to promise to work in congruence with her father.
This element of the story is easily my favorite. Rose goes from demanding respect to earning it. It’s lovely to see her journey come full circle. She goes through so much over the course of the book. If I had to choose a favorite, it’d be Seffy. She’s a shape shifter. I like how big and imposing she is. Plus, her transformations are always descriptive.
Even though there’s some goofy humor and shenanigans that a younger audience would probably like, I found this novel emotionally rich. Grief is a prevalent theme in the books, and it is done marvelously. I found myself missing Hina along with Rose, which is a testament to the author’s writing.
There was some technology and fantasy throughout the story, which I enjoyed as well. It’s not fully steampunk, but it is a good spot for those entering into that genre. Overall, I’d recommend this book to a middle-grade audience. It would be a bit challenging, but the story is addictive enough to get a young reader’s attention.
Rose Moriarty, is a part of an elite girls school who fight crime and solve mysteries of the otherworldly kind. Set years after a tragic accident, some of the girls reunite to solve a case with Dracula himself. Rose is haunted by her past as she tries to move into the present by reviving old friendships. Will Rose be able to right her wrongs, or will she continue to push everyone away?
Fans of both newer stories such as Enola Holmes and The Sinclair Mysteries or classics such as Sherlock Holmes, Frankenstein and Dracula will enjoy this modern take on James Moriarty's heir. There are many twists and turns that build the storyline and connect some our most loved fictional characters.
This was an engaging read that I finished in less than 24 hours. I enjoyed unearthing who all of the girls were related to and finding out pieces of their backstories. The writing is perfect for YA readers but engaging enough for even more advanced readers.
Thank you Sourcebooks Library/Stonefruit Studiio for a copy of the ARC.
4.5 ⭐️
she's the daughter of sherlock holmes' greatest enemy. she became a hero anyway. 🕵️♀️🖤
rose moriarty. teenage monster fighter. crime solver. moriarty's daughter. yes THAT moriarty. 😈
she built her reputation from scratch. in spite of her name. maybe because of it. 💪 and then her headmistress vanished. and rose — who solves everything — couldn't solve this one. 😶 school: shut down. 🏫❌ classmates: scattered. 👋 rose: completely on her own. then the worst day gets worse: an old friend is dying. 💔 AND a shadowy count named christoph shows up at her door with a ward named clara and a bag containing an ancient orb of incredible power. 🔮 rose already knows why they're there before they say a word. (she's a moriarty. obviously.) 😏 but the questions keep stacking: can she convince these strangers to help save her friend? 🤝 what ARE the grotesque bug-shaped creatures stalking their every move? 🪲😳 and how does she pursue all of this while avoiding a certain boy from her childhood? 👀🙈 oh and one more thing — professor moriarty wasn't the only famous villain to have a daughter. 😳🖤 historical monster-hunting mystery with legacy villain energy and a girl who rewrote her own story? we are absolutely not okay. 📚🔥
I loved this story. A mix of horror, mystery and fantasy and the cast of characters? Chef's Kiss. The children of mystery and horror figures: Moriarty, Watson, Moreau, Frankenstein and more, are on an adventure, trying to solve the mystery of who wants to kill Dracula, what happened to their teacher Hina and more. I cannot wait for the sequel!
Enola Holmes meets Lockwood & Co (GUYS I LOVE LOCKWOOD & CO AND HAVE BEEN SEARCHING FOR SOMETHING SIMILAR 😭 FIIIIINALLLYYY)
🩷 I loved the characters they brought in. I love the light romance plots, nothing too heavy and super focused on romance. Adored the historical references. I absolutely love that they let me figure stuff out. I can follow along and act as if I am also there with the characters for all the twists!
🩷 I did notice the story was a bit more on the tell than the showing side and that peeves me. I love it when they give me descriptions to really show emotion, or events, etc. That's honestly it.
🩷 I would totally recommend this for any YA (or adult) readers who love historical romance that brings in all the classics with a twist. If you enjoyed Lockwood & Co. and want something close (even if its not super close), this is a fun read! I rarely find things too similar but this is close enough.
This was my first time receiving advanced access from NetGalley, and this title did not disappoint in the slightest! I was intrigued by the title and the summary had me hooked! Truthfully, the first two opening chapters were a little underwhelming, and it bordered on a lot of telling versus showing-- but somehow, it kept me reading! I didn't want to lose hope! By chapter three, things really kick off and I totally underestimated Morgenstein's skillset at propelling the story forward. There's mystery and suspense, but the author does a great job of injecting levity without oversaturating it with humor. Although my book preferences lean towards YA as it is, I can even see older teens and even actual "adult" adults enjoying this light-hearted read. I loved the characters and all the call backs to other famous villains in literature. This was a refreshing story, and I will definitely be promoting it at my library.
I knew going into this book that I was not its intended audience. But I love YA books still, and I was absolutely stunned by how fun this was to read.
Rose reminds me of Enola Holmes stories, crossed with some Veronica Mars, steeped in some Buffy, and dribbled through something like Lockwood & Co -- basically a mish-mash of a ton of different things that I really love. It was exciting and mysterious and I fell in love almost immediately.
The discovery of each girl's father is like a fun little tribute to the books that came before it. And to sit and watch them all grow up and show us their strengths on the page was really fun. I need a second one -- or a whole series!
I definitely would recommend this to older teens, though it's definitely more for 14+ rather than the 10-12+ that YA is usually intended for.
a new young adult mystery/historical fiction that is well rounded enough to enjoy as an adult as well as a teen!
My daughter and I both enjoyed The league of Dangerous Young Ladies by J.a. Morgenstein. The story follows Rose Moriarty, who pairs up to to fight supernatural threats.
The book has great pacing in the adventure so you don't lose your interest and has a lot mystery that keeps you guessing. The overall feel of the book was definetly enola holmes vs buffy which is two of my favorites. You will love the found family aspect as well as the supernatural mystery....think a little historical fiction, supernatural dark academia. A perfect mix. The ending will leave you needing the sequel, which is out in August!
Thank you sourcebooks, stone fruit and the author for this gifted Arc, this review is my own opinion and really enjoyed this story.
I mean, I was expecting this to be a lot of fun, but I wasn't expecting to love it as much as I did. I had a really fun time with this! I sped through it.
It is technically YA, so I did find it very easy to read (and easy to read fast).
This is A Good Girl's Guide to Murder meets Sherlock Holmes. Literally. This follows the daughter of Sherlock's nemesis (as well as many other iconic literary figures) as they solve crime and get into shenanigans.
This really was so much fun and I think anyone of any age demographic would enjoy this.
Thanks to NetGalley for the e-ARC of this book in exchange for my honest review!
This was a very fun book filled with friendship, mystery and adventure! The cast of characters are children of famous parents like James Moriarty, Dr Moreau, Victor Frankenstein and Nicholas Tesla. The young women have been through an investigation/ adventure that turns out badly and ends up with the girls splitting up. They are brought back together in trying to find one of their instructors who disappeared on their ill fated investigation. i really enjoyed the characters and their story. I look forward to the next book. Happy reading!
I thought about going with a four star, but realized I just had way too much fun reading this to give it less than a five. It didn't change my world, but i loved living in theirs!!
WOW!! Absolutely wild ride. The characters are great, the action is almost non stop. The nods to other characters and books is fun. And I for one can't wait to go on more adventures with these ladies and a few of the selected gentleman that get to join them. ( I almost said serve them.....lol)
This book was not for me, but I did make it all the way through. Final thoughts: it’s annoyingly derivative, the plot’s a mess, there’s no clear moment of Rose “coming into her own” as the leader of the group, Clara’s a delight, the author really tries for some good things (they just need refinement), and the ending left a lot to be desired. For daughters of famous criminals, mad scientists, and monsters, it’s interesting they have so few shades of gray… 2.25 Stars.
[All that said, I’d see what the next book has to offer.]
The League of Dangerous Young Ladies is a fun nod to classic literature as the daughters of James Moriarty, Dr. Moreau and others join Count Dracula to fight monsters and solve the riddle of a mysterious artifact. There are bad guys, mad science, clever deductions and a sprinkle of romance. The end is not the end, but the beginning of another adventure, so I am sure we will be seeing another book(s) in the future. This is a squeaky clean book appropriate for middle grades on up.
I received a free advance reader copy. All opinions are my own.
Featuring Rose Moriarty, the daughter of Sherlock Holmes' sworn enemy, this is an entertaining story that is something of a mashup of genres, from mystery solving and mysterious cases, to monsters and mystical happenings.
Rose is an engaging protagonist and this story will appeal to readers who enjoy mysteries and mayhem as much as they like paranormal perils to feature in a book, all written up in a swashbuckling style. It gets 3.5 stars.
I received a free copy of this book from Netgalley in exchange for an honest review
This super fun, campy fantasy adventure pulls together the offspring from tons of classics you know and love! The characters are fantastic and the story is non-stop action as the protagonists are attacked by giant bug people en route to their quest. The ending is decisive and excellent, and the campiness will keep you laughing, even through all the bug guts. This book is perfect to hand to teens from grades 8 and up and even older teens and adults will enjoy the story, thanks to all the references to Classic Literature. Buy this! Read it! You won’t be disappointed.
First of all, I don’t like human sized bugs. I feel like this book is meant to be an Indiana Jones plus steam punk, girl power combo, with some supernatural stuff thrown in. That’s a lot to take on. Unsurprisingly, the book doesn’t get there. The characters aren’t as strongly shown as I would like them to be. It’s about 300 pages long which I think is a lot for what it is. Also, I’m so done with romantic, elusive vampire males. Why is arrogance in men viewed as sexy? Blergh. Limited applicability in the classroom.
This book was such a fun read, and I loved how it used Sherlock Holmes’s universe, as well as a few others, while still giving it an original spin! I also appreciated that it didn’t turn Sherlock Holmes into a complete idiot (unlike another book I read recently that also tried to rework Holmes’ universe).
Also, props to the author, I initially thought it was written by a teenage girl, but was surprised to learn it’s actually an adult man! He did a great job capturing the different heroines’ voices.
If there’s a second book (which I’m hoping, based on that little wink at the end), I’ll definitely be reading it!
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.
Amazing from start to finish! This book had me hooked right from the beginning and I devoured the entire thing. This was such a fun and creative spin on a world featuring the daughters of characters we love from literary fiction.
As a long time lover of YA books, I went into this knowing it was for the younger teen audience and I loved every page.
Strong female leads, awesome magical elements and a hint of romance - this is a must read for any fan of YA fantasy!
I loved this original take on the classics—including the historical time period—mixed with fantasy elements. The world building was amazing and added to the entertainment value without slowing the story down. It set the scene for a brave and empowered heroine and her new friends. The content is great for YA readers of all ages without the dark adult themes you see in some of the romantasy storylines.
this was so so good! i love love love jay and rose and the şloww burnn ••. the found family in this book is so wholesome with lovable imperfect characters. the only reason it's not a five star is sometimes it felt like we were getting told what was happening and not figuring it out in our own! i also don't love the bug people and i was slightly confused at some parts specially the vampire plot twist...
