Mori is out for revenge. Imprisoned in the English countryside, with her brothers held as leverage, she’s never felt angrier or more helpless. When an opportunity for escape arises, Mori takes it and flees back to the streets of London, where she is finally able to plot the demise of her recently freed father and his cohorts.

Start your review of Final Fall (Lock & Mori, #3)
For me it was always hard to resist a Sherlock Holmes retelling, especially when it is about Holmes and Moriarty. The story of two mortal enemies and how they became to be the enemies is what caught my attention a few years ago when I first noticed Lock and Mori. The more alluring this story seemed as Holmes and Moriarty are not just enemies - they are lovers; Moriarty is a girl and I found it quite an intriguing idea, making everything more dramatic and preparing my poor heart for a heartbreak ...more

Final Fall is the third and final installment in Heather W. Petty's Lock & Mori trilogy. As the story opens, Mori is Alice Stoke's captive having been taken from London to the English countryside. She's kept in a cage away from her brothers who are being used as leverage to keep Mori in line. With Alice's real threat of taking her brothers to America without her, Mori must bide her time and scheme

This book was so disappointing compared to how amazing books 1 and 2 were. I had such high hopes for Final Fall, and I was let down. Following her kidnap by Alice at the end of Mind Games, we meet Mori in captivity. She doesn't know how to get out, find her brothers, and keep everyone she cares about safe. That is her biggest wish, and Alice is training her to be a weapon to use against her enemies. Most of this book surrounds Mori, with Lock hardly playing any role, at all. I really missed him, ...more

Like a bad Saturday night scifi channel movie, I got into this in spite of myself. It's poorly written, poorly plotted, and totally outrageous. But the conclusion was fun, and I like that it was like a prequel to the story of Sherlock and Moriarty's rivalry. ...more

After liking the second book I was hoping a lot from this one. This was a disappointment. The storyline was so dull. The reason for Mori and Lock being enemies is so lame honestly. Mori being an honourable shit by doing dishonourable stuff was so annoying. Her refusing help just to save loved ones was so pointless and masochist. Lock is sooo less in this book. This is no fun at all. Unrealistic and frustrating. Ik it was very little possiblity for a HEA (cuz Sherlock and Moriarty) but this endin ...more

Heather W. Petty's Final Fall (Lock & Mori, #3) was the PERFECT conclusion to one of my favorite trilogies of all time!

The third installment of this book picks back up right where we left Mori at the conclusion of Mind Games (Lock & Mori, #2). I needed to go back and reread the final chapter of of Mind Games in order to jog my memory; however, Heather W. Petty does a great job of reminding you of the pivotal plot points you need to know as the remainder of the story unfolds.

I read book one in the series as a Goodreads ARC, intrigued by the idea of a modern day female Moriarty (Mori) who has a personal connection to Holmes (Lock) before they became enemies. I enjoyed their fraught teenaged feels, so I picked up book 2 for more. I got book three just to see how it all turns out.

The strongest part of the series for me has always been Mori’s internal conflict. Mori’s life goal is to make herself and her little brothers safe from their abusive, alcoholic police officer

Final Fall picks up where Mind Games left off. Imprisoned by Alice, with her brothers held as leverage, Mori’s never felt angrier or more helpless. Mori creates and finds an opportunity to escape back to London, where she is finally able to execute the demise of her recently freed father and his band of corrupt officers. Lock and Mori are reunited, but it is bittersweet because Lock is still on his noble crusade to stop (save) Mori.

Mild spoilers ahead.

Final Fall starts off exactly where we left off. With Mori held captive by a person she once trusted. She must find a way to not only escape but help her brothers escape somewhere far away from the trouble her family's past has caused.

This book wasn't as fun as the first two. The book focuses strictly on Mori (with Lock barely making an appearance) and her decision to "clean up" the people who have wronged her and her brothers. While it still had the dark tone, there was no mystery to be had. It

This book was on the short side which surprised me since the second one averaged 300 pages. It ends on a satisfying and angsty, but also bleak note. At best, Mori is a morally gray character. I loved Mori as a character, she is hell bent on exacting revenge on everyone who has harmed her and her brothers or turned a blind eye to their abuse at the hands of her father. So, she justifies her killings. Mori is so fucking smart, cunning, and badass, just the things that comes out of her mouth! Super ...more
Featured in Series Salute: Lock & Mori on Intellectual Recreation.

I really like Heather Petty's Moriarty origin tale series. In Lock & Mori, the Sherlock Holmes and Moriarty characters are teenagers, and Mori is a girl and the two fall for one another. But, as this is Moriarty's origin story you have to know that Mori is going to have some really rough stuff. This series is so dark.

Final Fall is a great end to the series. And it's the darkest of the bunch. (Torture, isolation, murder.) It's

The events that have been pushing at Mori since two books finally reach a breaking point in Final Fall. The story opens with Mori in captivity, being held by Alice and trained to be a weapon. But Mori has had enough of being under other's control, and starts devising ways to change her state, get her brothers out and safe, and ensure they can have a happy life after all. But before that, she has revenge to take, and people to kill - and one by one, she transforms into a hardened creature.

Thanks to NetGalley and Simon and Schuster Children's Publishing for the opportunity to read and review Lock & Mori: Final Fall by Heather W. Petty! So much intensity occurs in this book that I had to ponder and process my thoughts before I could write my review. Mori is still amazingly strong, intelligent and brave and she continues to be the biggest advocate for her brothers. When the story opens, Mori is imprisoned by Alice and her paid guards while her brothers are being used to threaten Mor ...more

3.3/5 stars I loved the first book in the series - such a unique retelling of Sherlock Holmes! But the second and the third were each a slight disappointment, mostly because I disliked the main character Mori more and more. Because she went through tragedy and heartbreak, I see how she came out as the intended villain (specifically her namesake), but I wish that her fall had been a little more tender and slow so that we could appreciate her character more and better understand her decisions.

I felt like there was way more to this trilogy. I am a little disappointed, to be honest. The once again, the characters drove the story so well. I have lost a little love for our main protagonist, Mori, but I still would hold her in high regard. This unique trilogy is perfect for fans of the BBC Sherlock or mysteries in general. The whole trilogy would be amazing as a full read through. The first two books flew by and are incredible. The final one, unfortunately, was not as stellar. It was stil ...more

Actual rating: 2.5 stars. I went back and forth a lot with the rating for this one and I realized that my desire to give it 3 stars was solely due to the fact that I wanted this to be better. With only 200ish pages, there's never a chance to pause and take in everything that Mori is doing and has done. The pace is just too fast. Lock's decision for them to become enemies at the end isn't earned either because the entire book sees him trying to help Mori. The 180 is way too sudden and doesn't mak ...more

The problem with reading a story about someone who turns into a villain is that they actually have to turn into a villain at the end. That's why I have such a hard time enjoying books like that.

This was a pretty good book. I don't remember much of the first two, so I barely knew what was going on, but such is life. We don't have a lot of Lock and Mori together in this book, which is sad as they are so cute together.

But of course, the part I liked the least is watching Mori turn bad. She kills mu

In the history of Holmes & Moriarty, together they are always a recipe for disaster. Their games of cat & mouse often set them on paths of mutual destruction that one can't help but watch as the train wreck happens. This being said, going into this trilogy I still somewhat held out hope for a happily ever after, even if my heart knew it wasn't bound to happen. Overall, all loose ends were tied up & this was a solid way to end the series. It doesn't mean I necessarily have to be happy about it th ...more

More of a 3.5. Mori is out to punish those who have caused problems for her brothers and herself. But along the way she must also face off against her onetime friend and love, Lock. Can Lock talk her out of her plan and take responsibility for her actions or is she too far gone? Mori must decide who she wants to be and what she is willing to do to protect those she loves.

While in the past I have loved these stories, I just had trouble connecting with this one. I am said this is the end. I would

I requested this book from NetGalley thinking that I had read the first book in the series. I had not but I didn't feel like I needed to read either of the first two books in this series to understand the story. There was some back story on why the book opens with Mori in a cell, trapped by her aunt and separated from her brothers.
This book focuses mainly on Mori and her search for revenge. We don't get a lot of "Lock" in this book and their meetings are... I guess the "bittersweet" from the bac

This was so disappointing. Spoiler alert: At the end these two aren't enemies, they're just teenagers who aren't dating anymore.

Mori becomes some sort of super villain, but Lock never gives up on her. Mori still loves Lock but tries to do things that will cause him to hate her. Big whooping deal. This does not set up a lifelong enmity where they fall off a waterfall together. This sets up a failed date to the prom. I hoped for a lot more.

I enjoyed this YA series and have enjoyed the idea of a female, teenage Moriarty. The first two books were fun (the first one was the best), and I've recommended them to students who have enjoyed them, but this final book fell flat for me. Lock barely makes an appearance, and I got bored. Of course I'll recommend this final installment for those who started the series and maybe they will like it more than I did. ...more

Mori has to escape from the prison that Alice has her in while also ensuring her brothers are safe. She goes back to London, determined to stop the threat. However, she must also face her feelings for Lock and protect him as well. Although I know in the class Sherlock Holmes novels that Moriarty is his nemesis, I was really hoping that Lock and Mori would have been able to solve this situation with their brain power.

This book was so great-and so sad! I wish that it was longer, but so much happened, and it was pretty heart-wrenching! I kinda hope we get another book with these characters, but grown up! After all, with the way things have set up, we haven't yet seen them as they are in the originals. I'd love Heather W. Petty's continued spin! ...more

I think this trilogy was an excellent villain origin story. While it did explain the background of Moriarty, it didn't necessarily try to make excuses for her behaviour. I really like when villains have their reasons for what they do, but at the same time we all know it isn't right and the hero still tries to stop them. ...more

I tried my very best to power through it but DNF after all. The first third is so incredibly boring it took me almost four weeks, then it gets incredibly overdramatic and just bad. Now I feel the desperate urge to sell my copies of vol 1 and 2. Thank god I got this one from the library instead of spending money on it.

I'm glad I hung in there with this series as I was not fond of book two. Book three was an easy read for me and even though Mori was not a likable character throughout the series, she had a believable motivation. If she was to become the nemesis of Sherlock Holmes, there had to be major trauma in her life and this book showed that. This book wrapped up the series nicely as well. ...more
