Recs if you like The Green Brain...

SFF featuring second worlds and storytelling that reflect and engage with hopes, anxieties, and imaginations about human activity and its influence on the environment + environmental justice. Always open to suggestions! (Note that I am using “second world” very loosely here, to mean both traditional second worlds and/or versions of Earth or parts of Earth that are so distant/strange as to be unrecognizable)

Books with druids as main characters or major plot points.

First books in series only. This could exclude series where druids appear in later books.

Note: may contain nature magic, herbalists, shamans and nature themed witches based on vibes
