- Octavia Butler might be for you.
- N.K. Jemisin, pick anything but if you ask for specific recs. start with the "Great Cities"-Books or her short stories collected in "How long 'til black future month"
- "This is how you lose the time war" by Amal El Mohtar & Max Gladstone, had some buzz last(?) year and is great
- Martha Wells, The Murder Bot Diaries.
Her other stuff is good to great as well, esp. her most recent, Witch King.
