If you’ve got a sci-fi or fantasy novel ready to go, then you might be in luck. The Ethan Ellengerg Literary Agency has put out a notice requesting novels in those genres.
While I don’t personally know anything about them beyond what’s on their website, I did check them out on Editors and Predators, and they came up as ‘recommended’.
It’s pretty rare to see a literary agent calling for submissions. They might be worth a shot.
The full details are on their website.
Good luck.
