Animosity, Vol. 1 by Marguerite Bennett

A sudden, unexplained change gives animals human-level intelligence and voice, upending society as once-domesticated creatures assert agency and wild species reorganize into new power structures; the collection follows a young human and the animals she cares about as they navigate a dangerous, morally fraught landscape of shifting alliances, revenge, and survival, exploring how empathy, violence, and leadership shape a world in which humans are no longer unquestioned rulers.
