Reminds me of Macbeth, with the forest moving towards the castle… A nice set up here – it’s the first and last paragraphs that grab me the most I think – the first with some intriguing context, and the last with that fantastic ‘claws out of the grave’ line.
The middle paragraph feels a little stodgy and slow – perhaps you could vary the sentence lengths a bit, just to break it up a bit?
Clearly it needs sequelling – I’d like to see you develop character now that sone kind of setting is in place :) Well done! MH
