Synopsis:

  Deep in the forest lives Mehrab the witch, coping with loneliness in her own strange ways and quietly battling her demons. One evening, a young woman appears on her doorstep seeking shelter, pursued by godhounds who wish to destroy all those practising magic, and Mehrab's solitary existence is disrupted as she teaches the girl how to control her powers. Together they forge a cure for their isolation with heartbreaking consequences...

Meanwhile, in the local village, children begin to disappear, sometimes returning forever changed – or not returning at all. Sinister offerings appear on Mehrab's doorstep, and a dark power pursues her through the trees. As the villagers turn hostile and the godhounds close in, Mehrab finds herself at the centre of a struggle to save the soul of the forest, the life of an old love – and her own new-formed family.

A bewitching gothic tale; haunting, gripping and written with wit and heart, this is a book to both savour and devour.  

My Review

A Forest, Darkly is a Gothic fantasy novel set in the Sourdough universe, written by A.G. Slatter, published by Titan Books. A multidimensional story that blends together horror and fantasy elements, which also reexamines and dissects age-associated roles, particularly in the female case, a self-contained plot that builds over how the past is haunting its characters.

Mehrab is a witch living in the woods outside of a village, a place where wise women and witches have been looked down on; however, she tends to those who ask for help, even if she's the last resource they will come to. She has found her balance in life, but when Fenna arrives with a woman seeking shelter, Rhea, both reluctantly agree to work together (and especially, helping Rhea to learn how to control her powers). At the same time, the strange disappearances of children from the village alarm the locals, and Mehrab starts sensing something evil stirring in the woods, and that has noticed the presence of a witch in the forest.

Part of why this novel is so enjoyable can be ascribed to the character of Mehrab; while Slatter starts from the classical figure of the witch, it is refreshing how she uses it as a way to break stereotypes, especially regarding ageism, and how a single woman can find her own place in the world; and in part, Rhea is also playing a role in breaking those insidious female stereotypes. In general, you could call this a story that serves as an ode to female strength with well-fleshed characters at the center.

As tends to happen with stories set in the Sourdough universe, you can expect multiple twists on classical fairytales, introduced subtly but which are recognisable once you open the eyes. In terms of pacing, we have a nice balance from the start, putting the emphasis on developing the characters at the center of the conflict while the plot still advances in the background.

A Forest, Darkly is another excellent novel, part of the rich universe created by A.G. Slatter; if you are looking for a Gothic fantasy with strong female leads, Slatter is the author you should pick. Can't wait to continue reading more stories in this universe!
