The Chalice and the Crown feels like a fairytale from the start, yet not the Disney kind. At times the story can be dark & grim; but Flamouri's beautiful prose and its mysterious storyline will keep you engaged.
Only minor spoilers to follow....
It is fascinating how Sasha is torn between worlds (I found myself creating a hundred different scenarios for how/why) and as the plot unfolds more mystery piles up. The ending is emotional; and as the moral dilemma is confronted and our characters' arcs reach their crescendo things avalanche down. Looking back I feel bittersweet; but love where the ending went.
It was reminiscent of reading a Katherine Arden novel, and gave me Nutcracker-type vibes mixed with dark fantasy. So if whimsical dark fantasy that feels like a grim fairytale sounds like a good mix (it is!), start here.
