There’s been a few reviews of Winter now, generally positive, so thought I might as well cherry-pick some quotes and put them here (with links through to full reviews in each case).

“it’s well-researched, intriguingly imagined, and it blends the worlds of
the occult and mysterious with the political and revolutionary in
surprising and colourful ways“

“Grace makes use of this freedom to give some passages a sense of poetry,
to not spell things out but simply offer lines of suggestion such as
what the green man is, or whether humanity’s fall, from a civilisation
about to reach the stars, signifies failure or simply a change in
direction, a chance to recognise old things stirring again.”

“Intriguing and original, Winter is a great little-ish read“

“The characters of Winter stand out vividly in my mind despite the short
page count. They are all given unique personalities and back stories
that I really want to know more about.”

“I found myself very intrigued throughout the entire novella.“

“The ending, when it comes, isn’t what I would call a real ending.“

Think that last one is meant as a criticism, but I take it as a compliment.
