I received an Advance Reader Copy from the publisher via NetGalley. This in no way impacted on my view.

Lock & Mori was one of my favourite books this year, and I couldn't wait to get my hands on book 2. When the opportunity came up to be a part of the blog tour, I jumped at the chance, so thank you Hannah, and the team at Simon & Schuster!

After the ending of Lock & Mori, Mori is now feeling somewhat safe. Her father has been arrested, and she and her younger brothers are safe from his abuse. How

Recommends it for: fans of Sherlock Holmes and a good mystery story

Actual rating: 3.5 stars

“I don’t know. Am I afraid of what you might be? Or am I afraid of what I know for certain I would be without the constraints of law?” He looked me straight in the eyes and asked, “Am I more afraid of you or myself?”

I don't know where I stand with this book and the whole series. From one side, it is quite an interesting Sherlock Holmes retelling where Mcs are Holmes and Moriarty. And as well as we know, Moriarty is Holmes's nemesis. So I definitely thought it's ingenious

Mind Games picks up shortly after the arrest of Mori’s abusive father … and even though he is behind bars she still doesn’t feel safe! The police have received anonymous tips that implicate Mori in the deaths of the Regent’s Park Killer and she has started to receive threatening notes at her doorstep. Thankfully she has the ever present Lock to lean on and help her figure out who is threatening her safety and innocence. His brilliant (if frustrating) mind will certainly be able to help her deter ...more

Another amazing book by Heather W. Petty, and a worthy sequel at that!

We get right back to where we left: Mori's father is behind bars and she's trying to piece her life back together.
Her mother's friend, Alice, comes to stay so the kids don't have to be put in the system, as we were given to hope in the last book.

Sherlock is trying very hard to patch up his relationship with Mori after the events from the last book and their relationship is super cute

And here we begin on the tragic descent into how Mori will become Moriarty, Sherlock’s nemesis. Book three is going to be a painful little thing, isn’t it?

Something good finally after reading so many 1-2 stars book! Phew. I really liked it that I finished it in a day (but it ain't in my ‘favourites’).

This was captivating and interesting. Idk why I just couldn't put it down. It wasn't the best book with blow-you-away mystery.

I was surprised at how good this turned to be. Maybe I had low expectations when I started it bcs of the first book? However, this was lot better than the first. The romance was complicated b/w the characters but I liked it. I

Sherlock and Moriarty, infamous enemies, are boyfriend and girlfriend in the Lock & Mori series. When we last saw these two, Sherlock betrayed Moriarty. I thought as I picked up this book, "She's going to try to kill him." That's what I surmised from their last meeting. She would never forgive for what he had done. But that wasn't the case. She is still pretty angry with him, he is stuck in his ways according to her, and they have to deal with the repercussions of the night she tried to kill her ...more

Is it too much to ask that these two get a happy ending, preferably together?

I found Mori's single minded pursuit of loneliness and becoming a villain underwhelming and not very intelligent of her. She's in kind of a tough spot by the end of the book, but you'd think that by now she'd understand that she can trust Sherlock to help her save herself?

This was just a frustrating read. I'd started this series hoping for a new look at the relationship between Sherlock and Moriarty other than (good/e

I'm probably still a little lost about this book, especially the ending. The ending was kind of a brutal blow for me, primarily because I didn't see it coming, but also gee whiz could the girl have *someone* sacred in her life? (Other than Sherlock. Because, well, we know that won't last.) Not sure how I feel; probably a 2.5. ...more

There's this weird thing with this trilogy. I have some sort of feeling where this trilogy is going. And I'm not entirely sure if that's exactly where I want it to go, or if I'd secretly wish the author would provide us with a different outcome. And that also makes me a little reluctant to read on and to pick up the next book. I had to gather some courage to read this book and I hope to find the courage to read the next one next week.

However, just like the first book this book was an amazing rol
3.5 stars.

I'm still reading this series even though I suspect it's going to end unhappily. Why do I do that? I felt a slight hope at the end of the first book, but I don't feel that upon finishing this one.

Mori frustrated me throughout the book; it's like she was determined to sabotage herself. I understand she didn't trust the police because of their camaraderie with her father. But running from crime scene after crime scene? She knew they'd discover the crimes and find evidence of her there, a
Mind Games open in the aftermath of the events of Lock & Mori, with her father behind bars and yet her not feeling safe. Firstly, there have been people who support him and think she is lying and secondly, there are threatening notes coming at her door. But most of all, someone is trying to frame her for the murders - by leaving evidence at her door. Mori has to handle all of this, and worry about the safety of her younger brothers, as her whole family is now tainted with her father's crimes. Sh ...more

I read book one in this series as a Goodreads ARC and picked up the second for another dose of the rather excellent feels generated by the teenaged couple that is Moriartiy (Mori) and Holmes (Lock) in this re-imagining of the Sherlock Holmes universe.

Like the first book, the strongest aspects are Mori’s internal conflict and the fraught relationship between Mori and Lock. We’re on a journey that’s supposed to end with Moriarty becoming a supervillain, so the author does a good job of taking a ba

This book is the second book in the series Lock and Mori, and it was overall a very boring book. The first book was more action sensed and actually flowed. But in the second book the main characters feelings, thoughts, and actions were scattered and didn't make any sense to me. The books main suspense is still there from the first book but in this one it just becomes uninteresting to the readers.

1 thing that I did like was that that author really did a lot with the characters thoughts and emotio

I picked up a hardcover copy of the book  from  (I paid for it myself). My personal review of the book is as follows:

This book feels so much more richer and complex to me than a lot of other YA books that I've read lately. I really liked how so much of the character development and plot growth was woven into the storyline as way of showing the reader another layer of the story and showing the ways/reasons why "Mori" could turn "evil" later on(I'm almost positive that "M

Book 2 in the re-telling of Sherlock and Moriarty. This book is definitely dependent on book #1 for full comprehension and appreciation of plot. If you are going to read this book, you need to read the 1st book beforehand.

I want to love this series, but Mori gets on my nerves soooooo badly!!!!!! She’s a genius and a mastermind, but she keeps making choices that have me shaking my head and wanting to yell at her through my Kindle!!! Yes, she is young. I get that. However, she wants

I have to say..... I didn't like this book as much as the first one.

Trigger Warnings: Violence, Abuse

Although I didn't enjoy this one as much as the first one, I did still really like it. This is a good continuation of the series. We pick up a little bit after where the last book left off.

My main complaint with this book is that it took over 100 pages into the book for what was being teased from the end of the last book to happen. I feel like the story could have gone better if it had happened e

I got this and the first one in a subscription box and honestly that’s why I read this one. I’m disappointed in the way Mori went from a strong and determined girl trying to protect her brothers to a whiny, self-sabotaging mess. Also the ending was a bit ridiculous and disappointing, I mean can the girl have someone besides Sherlock who just wants to protect her and not demand anything from her? I also feel like there is nothing to Lock, non of what makes him the Sherlock we all know and love.

I don't even know how to rate this one! Lock and Mori, her especially, are really compelling characters but I just felt so frustrated! The developments make sense, it all checks out for me and its written really well, but sometimes my enjoyment is compromised when it feels like the characters are just hurtling forward on a trajectory of sadness and discontent.

I decided not to read the third book in the series, but I still strongly recommend this trilogy especially if as a read
The story was quite exciting, a bit confusing yet ok. Mori on the other hand was more and more getting on my nerves. For a character who's constantly called brilliant she made a shitload of stupid decisions. That didn't help with the character development which just wasn't there. At the end she's at exactly the same point as where she started. Srsly, I hate those dumb and stubborn characters that insist on being bad for their loved ones so they do everything alone when just a little talk would m ...more

This book is 1 star up on its predecessor, but that's not saying much.

You really need to read the first book before reading this sequel since some important facts are not explained in the sequel, such as the details surrounding Mori's mother's death. Even I who read the first book a few months ago could have used some memory refreshing.

The ending left me unsatisfied because of the primary character's still unfinished business. Fodder for another book.

4/5 stars. Another great modern Sherlockian retelling, taking place in London!

November 28th can't come fast enough!!

Lock and Mori are at it again continuing to solve the mystery of who the Regent's Park murderer is. They have many leads, suspects, and this time help from Alice--a woman who was Mori's mother's best friend and is considered an aunt to Mori. Alice uses her elite, under-the-table like resources and promises to keep all of Mori's brothers safe. With her brothers taken care of, Mori c
I liked this one a lot better than the first one, but it's hard to feel a lot of suspense when I, a chronically terrible story-figure-out-er was able to figure out the villain, and most of the tension revolves around Mori potentially going to jail despite the fact that the police never once offer up a motive for her to be a murderer. But if you can forgive this book for being poorly plotted and stupid, you will probably be able to enjoy Mori's slow decline into madness and evil-villain-ness. ...more

This was the most boring book I’ve read in a looong time. Mori’s mental state was the most interesting plot point in the book. Unfortunately, I feel as if the author just enjoys dragging out a plot. Sherlock is about as interesting as a piece of stale bread. He has no real personality and I feel like he is there to further the plot and for Mori to make out with occasionally. The “villain” was very obvious to me, however, I am pretty good at figuring out The Who done it in a mystery. I will proba ...more
Featured in "The Story Continues: Three Sherlock Holmes Sequels" on Intellectual Recreation.

After nearly dying at her father's hands, Mori wants nothing more than for her father to rot in jail, but she knows that her James Moriarty is more than capable of hurting his family even from behind bars. Several of the police officers on the case are friends with Mori's father and would love nothing more than to poke several holes in Mori's story. Protestors are camped out in front of the Moriarty home,

How many serial killers can one book handle? That's a huge problem for this book and I'm not sure we're done finding them yet. However I love the relationship between Lock and Mori and will definitely be reading on to see which one causes it to crash and burn. I love the look at Lock before he totally becomes Sherlock, I think it's a brilliant characterization. ...more
