Wait, now that we're discussing this, I think Caves of Steel peaked my interest in investigatory fiction like Agatha and James' works... Okay, now we're delving deep down the Hole of Distraction.
"Pull out of that dive, AR! Pull out of the dive!"
Reading other genres, like reading in general, provide insight to a writer. Like an anonymous forum. Author So and So published this work about This or That. I've always had an idea about This or That, but in my head it went There and then There. Author Other Man published this about Gidget Widgets... I didn't know Gidget Widgets did That. I wonder, if they did That, with this other villain archetype, maybe they could do This. Doing This could then lead to There.
Get my confusing drift? That's okay, I barely hung on there myself. All I'm saying is reading, and reading outside your writing genre, can be helpful.
The book itself is an urban fantasy, I guess. (I've never been good a labeling, unless it's Agatha or James or Isaac.) In the story, she explores the fairy world. It's almost SFey in the way she explains how the fairy realm and human realm are interwoven dimensions with "doorways" to each other.
This story really revved my creative juices to forge ahead with a fairy tale story. I just need to really decide which one now. I want to try and find one that hasn't been retold at nausea in novels and movies. That excludes Red Riding Hood, Snow White, Beauty and the Beast, and Cinderella. I think I also want to take on the more grimmer Grimm telling of the story and push my grittier boundaries.
