| A cosy, brain-teasing mystery set to become your new winter favourite |

Charlotte Frost writes atmospheric cozy mysteries that shimmer with a warm festive glow, a hint of the fantastical, and a distinctly poetic voice.

Her debut novel under this pen name, The Ghost of Grimoire Castle, combines theatricality and wit with layered storytelling, weaving together elements of classic detective fiction, cultural allusions, and playful humour.

While entertaining and accessible, her mysteries carry a richness of style and tone that reaches far beyond conventional cosy crime. Originally written in Russian, her works are now being translated into other languages.

Charlotte Frost is only one of her literary identities: she also writes in other genres under different pen names, each with its own distinctive voice and vision.

Now based in Germany after living in several European countries, she combines a career in research and artificial intelligence with a restless curiosity about the world. Her passions are as varied as they are vivid: from reading, travelling, and translating, to yoga, mountain trails, art, and cooking.

This rich diversity of interests informs her literary voice, giving her mysteries their depth, poetry, and distinctive flair.

“If you enjoy the book, adding it to Listopia lists like Best Winter Mysteries really helps other readers find it."

Author: Charlotte Frost
Stars: 3⭐

My Review: This is the 1st time I am reading anything by this author. This might not be for everyone but I did enjoy it. It this was incredible, like a feast for the mind 🤓📚. Every page dropped some cultural gem - ancient China, art, philosophy, little witty lines hidden everywhere... The mix of serious and playful was really good. And the writing! Sometimes poetic, sometimes fast and sharp. Classic and fun rolled into one. Long? Yes and that's is why I gave it 3⭐
