Thoughts on this?
I've heard that you should choose two books in your genre to show that you read in your genre and that you're familiar with it and its market.
Beyond that, are there more specific guidelines that folks adhere to?
For example, I have one comp title that engages with themes similar to those in my story, while the other is more similar in writing style and tone than theme. Both engage with similar tropes and fall into the same sub-genre.
I also read an agent tweet that said that comp titles should be no more than 3-5 years old. One of my comps is over ten years old, but I'm reluctant to ditch it because it's otherwise such a great fit.
What's your strategy for choosing comp titles for your query?
