My Five Word TL:DR Review: To Put it Simply – Brilliant

I loved A Forest, Darkly. I would go even further and say this is my favourite Slatter book so far – but, I seem to have that feeling every time I read her latest work, she just gets better and better. This author is definitely my catnip and A Forest, Darkly is just what I’m in the mood for at the moment. A wonderful concoction of dark forests and witches with a boost provided by folklore, fae and the mystery of missing children, all wrapped up in a fairytale style with hints of Little Red Riding Hood. To be clear though. This is an adult fairytale, it’s dark and serious in places and certainly not a story to read to little ones. I would also mention that although this is set in the Sourdough universe this can be read as a standalone.
So, this story starts off with Mehrab. Mehrab has a history, things in her past that she ran away from and doesn’t like to dwell on. She ran far, far from home and ended up in a small cottage, tucked into the forest, not too deep to be at risk from anything too dark and not too near to the bordering village to have them watching her. It’s the perfect spot, and Mehrab has her life in order. Until two things happen almost simultaneously and cause upset, not to mention becoming the catalyst for change. Firstly, Rhea ventures deeper into the forest one day, chasing a rabbit, and becomes trapped. Clearly, something lured her in and if it wasn’t for her quick wits she could have been stuck there waiting for whatever might appear. Secondly, an old friend visited and brought with her a young woman, also running away from home and needing shelter. Mehrab takes in Rhea and becomes, begrudgingly at first, her mentor. Now, as this is playing out, it turns out that a number of children have gone missing from the village, some have been returned but seem not so much themselves any more.
What I loved about this.
Well, firstly, it’s beautifully dark, tantalisingly twisty and perfectly witchy. I love the way Slatter writes women.
They’re just so real – by which I mean, they’re not perfect. Mehrab is grumpy, curmudgeonly and yet alternatively wise and thoughtful. She sometimes takes her own sweet time to come round to an idea but she eventually gets there. Rhea is young. She’s impulsive and stubborn but she does listen and she takes pride in Mehrab’s praise. The two go well together and start to forge a firm bond. In fact one of the really enjoyable aspects of this is the ‘found family’ feel as Mehrab gradually seems to gather more lost sheep into her flock.
The setting is great. We obviously spend a great deal of time in the forest and the writing is so evocative. There are dark and twisted elements but also beauty and it’s all tempered by the warm cosy cottage. Meanwhile, in the village, people are starting to become scared. Their children are being taken and although they’re being returned – they’re different. On top of this there is the persistent fear that things are beginning to change. Folklore and religion don’t sit well together at this time and witches and wise women are hunted. Given that both Mehrab and Rhea are running from mistakes you can feel that it’s only a matter of time before they become ensnared. Mehrab is starting to feel the itch to move on but she is also desperate to salvage the mystery of the missing children.
Then we have a dark entity, a horned hunter who seems to be stalking Mehrab, for reasons unknown. She’s taking as many precautions as she can but there’s a dark ominous feel to the story like it’s only a matter of time before this creature succeeds.
Finally, I loved the imagination. The Sourdough universe is full of all sorts of wild and wonderous critters and A Forest, Darkly is no exception. We have a shadow creature of the Wild Hunt, changelings, critters that live in the lakes, green women, summer husbands and much more.
I absolutely adored this book, I wish I hadn’t read it so that I could have the pleasure of reading it for the first time again and I have no hesitation in recommending.
I received a copy through Netgalley, courtesy of the publisher, for which my thanks. The above is my own opinion.
My rating 5 of 5 bewitching stars
This sounds amazing: dark forests, witches, folklore, fae, disappearances and a variety of creatures. So many features that call to me!! Plus I really appreciate a grumpy character from time to time. They tend to be entertaining and sometimes even oddly endearing. Lovely review. I majorly need to start picking up the books set within this world.
Well, I completely agree. I think you would love Slatter. She’s such a good storyteller and I love this world she has created. You have such a lot to look forward to.
