A.S. Greenleaf (they/them) is the queer, neurodiverse author of the upcoming sapphic mythological fantasy I Choose the Bear. Their work draws inspiration from their Finnish-Irish heritage, as well as their long-standing interest in languages, myths, and little-known histories. When they are not writing, they enjoy playing Hollow Knight and practicing qi gong.

They are represented by Francesca Ali at William Morris Endeavor.
