Rounding up because it was definitely worth the read.
A Certain Slant of Light was a beautifully written story. I thoroughly enjoyed both the writing and the overall story. It presented a different and original take on ghosts than any other I have read. While there were some stretches where I lost focus and had to go back to re-listen, there were also longer stretches that I was so engrossed in the story, I found it difficult to stop and leave my car.
The ending left me feeling a little... unfulfilled, maybe? Not sure exactly what I was hoping for, but compared with the pace and buildup of the rest of the story, it felt too neat and tidy (at least for Helen).
Overall, I would certainly recommend one giving it a try. I plan on reading the companion novel to see how things turn out for Jenny and Billy.
