After a quick search, I notice that there's a book titled "As Pelejas de Ojuara" by the Brazilian author José de Alencar. He's known for his novels set in the Northeast of Brazil and often features indigenous themes. Ojuara is a character in one of his works. Wait, actually, José de Alencar wrote a novel called "O Juara" which translates to "The Warrior" but maybe there was a mix-up in the name. Alternatively, maybe the title is a play on words.
