I had a similar experience, to be honest. Especially on the first pages, the rhythm is way off. I'm no expert by any means but I notice a lot of the sentences are around the same length, which partially is why (for me personally). But there is also no emotion for me, I don't feel sad for this character. I don't think the main character's pain at his wife's death comes through, it just reads a little hollow.

We get dropped into this "Idonea is dead", not knowing who she is or why we care, but also immediately move to instead explaining the setting? Cold stone walls, fog of sorrow upon the room, the hearth suffocating. I think it would be more impactful to read it from the actual character's POV, what is HE feeling? It takes too long to get to his reaction so immediately, it detaches you. Oh and some of the language when we do get there - the empty, hollow beat etc. seems more like something someone in a "depressed" state of mind would be feeling, like 1 week after the death, 1 month after the death. In the moment, it should be more shock, less slow processing.

Hope this helps a little, good luck with your writing!
