This is the 2nd book in a trilogy that I would describe as urban fantasy / horror / mystery.

There is a lot of action/violence/horror and yet the pace of the story is quite slow and contemplative. Our main character Alex Locke is forever questionning what's going on and looking for answers...especially regarding the time travel element which is pretty perplexing to be fair!
I like the pacing as I hate to be rushed through my stories but others may not agree.

All Alex wants is the return of his kidnapped daughter and in order to do this he must have the obsidian heart - but at what cost?
It all ended on an abrupt cliffhanger and now I have to know what happens...I was going to name this in my 'favourite series' tag but it all rests on how the third book comes together...

No pressure 😂

I read the first book in this series, The Wolves of London, and enjoyed it immensely.
While this second installment had ample action and intrigue to keep me reading, some parts dragged on a little for me and the bits where Alex contemplates the complexities of time travel were sometimes rather brain-hurty.
Still, while I lost track of what was going on at times, the ending was tidy enough (and tense enough) to persuade me to read the next in the series upon release.

I read the first part of The Obsidian Heart trilogy, The Wolves of London, last year on a whim. I knew nothing about it and picked it up solely based on the fantastically gothic cover. It was an absolutely brilliant book that left me wanting more. Now, the second part of the trilogy is upon us and the good news is that it’s just as good as its predecessor.

When we last left Alex Locke and Clover they were stranded in Victorian London. Book two picks up some time later. Both have slowly started to adapt to their new lives. The fore knowledge they share making living in the past slightly easier. That said, there are still issues. Clover is finding it especially challenging; 19th century attitudes to woman being something of an anathema to her.

Living as a gentleman in polite society should be a breeze after all the suffering he has endured, but Locke doesn’t have a second to let his guard down. He is constantly on the lookout. He knows the Wolves are out there somewhere, so whenever the inexplicable occurs, Locke is compelled to investigate.

All the while Locke continues the search for his kidnapped daughter. Ironically on his journey he has gained a new surrogate family. Clover has become his de-facto wife and partner. Locke has also become the guardian of a young girl he names Hope. The delicate bond that forms between the two is particularly well realised. The Wolves have performed horrible experiments on the poor mite and she is used to being treated like an animal. As Locke and his friends help her acclimatise to freedom, you can see a genuine tenderness develop.

Locke is getting more and more desperate as time ticks by. The following questions still remain, what do the Wolves of London want? Why are Locke and his family key to their plans? And who exactly are these new players in the game, the enigmatically named Society of Blood?

Morris does a grand job of blending together some complex time travel and multiverse theory. The more Locke uses the Obsidian Heart, the more he agonises over the consequences of each and every action he takes. I love that older versions of Locke pop up from time to time, excuse the pun, and give the current incarnation of our hero advice. The deeper Locke travels down the rabbit hole, the more complicated things become. I always worry a bit about time travel in novels, it strikes me that it is potentially quite easy for an author to get tangled up in knots when it comes to a labyrinthine and convoluted plot. No need to fret in this instance; Mark Morris manages to pull off the intricacies of time travel with aplomb.

The narrative is peppered with some gleefully horrific moments. The streets of Victorian London are a dangerous place. Violence and death round every corner. I’ve been thinking about it and I’ve to a startling conclusion. I believe Mr Morris delights in lulling his readers into a false sense of security. Just at the moment when you are completely relaxed and his writing has got you entirely in its thrall he throws in something epically nasty. I love it.

One word of advice, if you haven’t read The Wolves of London first I would strongly suggest you do. The Society of Blood is best appreciated as the second part of a much larger story. I strongly suspect I’ll appreciate even more once I have read book three. I have a few suspicions about where this tale is going and I am burning with curiosity to see if I am right or not.


The Society of Blood is published by Titan Books is available now. The Wraiths of War will follow next year. I genuinely can’t wait to discover how the final part of the trilogy is going to play out. I’d happily recommend this series to anyone and everyone, Mark Morris is writing up a hell of a storm.

This book and its predecessor - The Wolves of London - made me wish I had read some of the negative reviews. I got them on a “two for the price of one deal” otherwise I wouldn’t have started this one. I gave up at the point where the characters start discussing the absurdity of the plot.

I think you could safely skip the first book and start straight with this one. That would save 13.5 hours of your life which you could do something enjoyable with. All you need to know is there is some time travel involved, and the main character is looking for something. The style is reminiscent of Dickens, in that he appears to have been paid by the word, and Conan Doyle, if you can imagine a Sherlock Holmes story where Sherlock does not exist and the only protagonist is Dr Watson, who doesn’t understand anything.

At any point where urgent action is required, the protagonist spends several minutes (audio version) debating various causes of action. He will then discuss some of them with another character, then ultimately fail to act decisively.

Two thirds of the way through this second book, the protagonist and I still have no idea really what is going on. When the story is moved on, the impetus comes from without, not the characters.

What might you like? The audio book is well read, by Ben Onwukwe, he has a pleasingly deep, gravelly voice, and he keeps the volume consistent, which not all readers of audio books do. There are some elements of fantasy horror if that’s your thing. If you are fascinated about the conundrums posed by time travel this could also be your cup of tea.

Where for me the previous book started very strong and then delivered ever diminishing returns as it became more clearly fantastical, this second instalment does nothing to re-engage me. Set primarily in the Victorian era (while failing to make much interesting use of the period), the story grinds almost to a halt where it should spring forward. Characters examine options, discuss implications, speculate aloud and to themselves endlessly about what might or might not have just happened/be about to happen, and get very little done. Some things do happen to them, but everything is external – the protagonists have lost all momentum of their own. I stopped caring halfway through and really had to push hard to reach the conclusion. There’s still potential in this series, but after a novel’s worth of pacing and navel-gazing I’m out.

This is a difficult book to review. It's the middle of a trilogy so I can't tell whether it's done it's job. I found the first book so intriguing I had to read the rest. The second is as interesting though maybe not quite as compelling, but it doesn't necessarily have to be if it is, as it feels, setting up situations that will reach a satisfying completion in book three. That's a question I cannot answer until I pick up the next book. What feels disjointed may serve a purpose. In a sense, it partly does already in that the reader gets a sense of the Alex's disorientation. There's only one way to describe the book and that's as a time-travelling steampunk horror. With time-travel, horrific mechanical creatures, mad scientist experiments, shape-shifters and a strange artifact at the heart (excuse the pun) of the story, it's difficult to tell whether the story is overdone or perfectly executed at this stage; but, as a reader who likes to see a wild imagination at work, this is still a good read and, if the trilogy concludes in a satisfactory way, may become three volumes that are a welcome addition to my bookshelves.

I may have pulled a brain muscle reading this. Rarely have the implications of time travel been so thoroughly explored, stretched and pummeled. If the subject wasn’t so fascinating, I would have said it was a detriment to the story. However, the characters were strong and interesting and the mystery was teased along to the final page. Now I have to get my hands on the final book—a whole lot faster than I did this one. Several months between books one and two was far too long in a tale this complicated.

Alex Locke is still searching for his daughter in Victorian London, finding that he's beginning to get used to the world he's now living in and searching for more information about the Society of Blood and the obsidian heart.

I was a little trepidatious about this, often time travel stories have a lot of issues.but this one acknowledged a lot of the issues and worked with them. It was interesting to see what was going on and how the characters worked with what they had. It left me wanting to read the next book.

Lots going on in this book, but very much just filler to get to the finale of the trilogy. No questions are really answered and is full of speculation as to what is going on - which leads me to think not even the author was sure.
It definitely portrays the confusion experienced by the lead character, but also succeeds in confusing the reader, which isn't great. Might have been better delivered if not written in the first person.

This was an enjoyable follow up to the first book in the series. Most of it is set in Victorian London, and the dank, smog, dirty feel came across nicely.
There were a couple of 'what!' moments, where i got a little confused - but i suspect most of these will be completed in the third book.

Had to read it just to see what happened. Full of cold and feeling sorry for myself it’s a quick easy reading and I think I’ve sussed out already how it ends. But, it’s good and not too taxing. Different.

A bit more happens in this one, but our protagonist is still haphazard and clueless. We are two books in and no nearer to an answer, any resolutions or sensible actions. Feels like a filler book.

This felt like a middle book (which of course it is) an everything is very confusing currently. I’m hoping book 3 will tie everything together convincingly.

This is the second book in the series and to get the complete story all three books need to be read. Pretty decent steampunk/gothic fantasy/horror.

Following on from The Wolves of London, The Society of Blood brings us back to our main protagonist, Alex Locke, as he attempts to acclimatise himself to the way of life within Victorian London. Unsure how long it will take him to find his missing daughter, Alex occupies his time creating connections (watchers) in the hopes of finding the lost obsidian heart, whilst simultaneously keeping up appearances of a well-to-do family man. Concerned that the Wolves of London will seek him out at any moment, Alex is on edge – getting his hopes up everytime a new lead comes through. But little does he know that he will encounter a new enemy in this world, the Society of Blood.

With Mark Morris delving deeper and deeper into the ways of Victorian London within this novel, I find myself feeling more nostalgic towards The Apollonian Case Files by Mark A. Latham. I mentioned this in the review last week for the first in the Obsidian Heart series, and it flows through into this novel with Alex and Clover submerging themselves within Victorian society. Morris brings to life the dark, gloomy, and sinister atmosphere of Victorian London: buildings covered in soot devoid of any true colour but black or grey, dense mist and fog covering the city streets with visibility severely reduced, and – one I feel I must mention – the lack of concern and curiosity within the people of this era in relation to brutal murders of innocent people. This all added to the atmosphere that Locke was being followed by a presence that clung to the shadows, only emerging when it truly needed to or to instill fear into the heart of Locke, or Clover.

In the confusion of it all, Locke and Clover use much of their time trying to understand the powers of the obsidian heart and the ways in which the many Locke’s have used it. It becomes clear that Locke has been travelling back and forth in time by the very nature in which he meets and encounters people, especially friends and associates. Many of those he meets in Victorian London, are people he has encountered before in his excursions through time, having now hired them out to help him in exchange for coin. Not only are Locke and Clover confused by the ways in which he has travelled (with some of these visits having not technically happened, but have in his future), but I found myself trying very hard to understand the concept of multiple Locke’s, or even one Locke entering many different time periods, parallel universes, or multiverses. Morris attempts to explain the thought processes behind Locke travelling back and forth and, in the way he describes it, it makes almost complete sense. But I wouldn’t be able to tell you how as it burns my brain out just thinking about it! It was this element of the novel as well, that reminded me of Latham with the ability to travel through portals in time within his novels – ironically, back to the Victorian era as well.

Locke and Clover develop further in The Society of Blood; with their deceptions to the people of Victorian London, and understanding that, in all intents and purposes, they are alone in this world, the two grow closer as they pose as a married couple with good standing within society. Locke has always had trust issues with Clover due to her relations with Benny and the type of business she previously partook in. But, with the current situation they are in, it becomes clear in the way that they act towards each other that the trust issues are slowly falling away. In some moments, I do also get the feeling that they are becoming closer in terms of their relationship as well with their reactions and actions telling the tale in that respect.

As I seem to find with most novels within this genre at the general plot-line, I found this book easier and quicker to read than the first in that I was more aware and understanding of the events taking place, and could understand why, and who, was after them. I am intrigued to see how the next novel continues on from Locke and Clover’s current situation.

A good, fast read. I didn't enjoy this quite as much as the first book in the series (The Wolves of London), but possibly that's because it suffers from being the second book in a trilogy. Even so, it was still very good.

Alex is stuck in the nineteenth century with Clover; he's adopted a little girl whose mechanical arm is going to kill her unless he can get her some twenty-first century medical help; and someone, or something, is killing people connected to him. And he still needs to find the Obsidian Heart.

The thing I liked most about this book was that - since it doesn't have quite the frenetic, panicked pace as the first book - Alex has time to stop and think about time travel. Unlike most authors, Morris doesn't have any hang-ups about having two versions of the same person in the same place at the same time. This means that Alex has to deal with the concept that you now is a different person from you then and what happens, really, when you change the past - or the future? Are there limits, or not? And what happens to the future that has now been changed? What, exactly, is time?

I'm very much looking forward to the third book, which will hopefully reveal some of the answers to the questions.

Trigger Warnings – There is a lot of child abuse, especially involving horrific experiments on children including the forced amputation of limbs.

This was my favourite book out of the three books in the Obsidian Heart trilogy and it had a lot to do with it being set in the Victorian era rather than the present day. The first book was primarily Alex Locke running around trying to get his bearing as his life fell apart after his daughter is abducted. In this book, he’s still chasing his tail a bit as he’s coming to terms with what strange and supernatural creatures really exist in the world. However, we see him come into his own as he starts to make plans and start to work things out.

Unfortunately, I also began to start to work things out and piece things together which meant that by the end of The Society of Blood I had worked out most of the trilogy’s overall plot. It didn’t stop the book itself from being enjoyable, but for me, it did affect my feelings toward the final book.

This is the second part of the Obsidian Heart trilogy, a fantasy / horror / time travel / multiverse adventure. I remember reading the first book last year, I think I remember liking it but don't remember that much more, so getting back into the series was a bit confusing at first but most of it did come back to me, helped by recaps from the author.

In this one Alex is in Victorian London trying to find the Obsidian Heart in an effort to find his daughter. I particularly liked the descriptions in this part, about how grimy and smelly London was, it was all very atmospheric and the action was quite fast paced but as the book progressed it got a bit bogged down with the characters discussing the nature of time travel and what to do next, so it began to drag a bit. Still, I will be reading the next book.
