You never know what kind of stories an agent is looking for. Most agent have a #MSWL or manuscript wish list. A lot of these lists are posted on their Publishers Weekly profiles. If you’re looking for an agent follow them on Twitter and check out their wish list.
Right now, it seems like agents and publishers are looking for fantasy novels and diverse subject matter like stories LGBTQ teens or other underrepresented stories. In the end I always believe it’s important to write the story you need to write. You can also find agents by looking at the acknowledgement page at the each of your favorite books. Authors always thanks their agents.
It takes some work but it’s worth it. Good luck and happy writing.
