Alternate History Genre and Agents

What type of agent would you query if your book is an alternate history story. I’ve seen this sort of story labeled as a sub-genre of sci-fi, fantasy, and historical fiction- so when looking for an agent on Query Tracker, how does one choose?

If it weren’t alternate history what genre would it fall in? Is it action? Romance? Mystery? Fantasy?

Action\Adventure. I wouldn’t call it too high powered on the action though. Not like what you would expect of something that had a super hero for example.

I would target agents that rep books similar to that, even if they don’t have alternate history.

All right. Thank you.
