Indigenous novellas suitable for grade nine/ten?

I'm looking for Indigenous novellas (under 100 pages) written by Indigenous authors to use in my grade nine and ten English class.

I've been using Nnedi Okafor's Binti for older grades, but need something more suitable for the 9s and 10s.

I'm open to any Indigenous author from any culture. If you know of any that focus on the concept of Two-Eyed Seeing or living in multiple worlds, I would appreciate it!

Thanks!
