Not all of it is based on true stories. It's a mix of fictional elements and possible inspirations from real-life incidents, but it's not a straightforward documentation of actual events.
Unfortunately, without more research or prior knowledge, I can't tell you the author of this 'amor de mae novel'. It could be an independent author or from a small - scale publisher. There are so many works out there, and this title doesn't immediately ring a bell in terms of a well - known author.
I'm not sure specifically as there could be many novels with this name. It might be about a mother's love. Maybe it tells the story of a mother's selfless love for her children, her sacrifices and the strong bond between them.
The title 'la guerra sucia' gives some clues about possible themes. One theme could be the corruption that often accompanies war. This could be in the form of military or political corruption, where people in power use the chaos of war for their own gain. Another theme could be the destruction of innocence. War has a way of shattering the lives of the innocent, and this story might explore how ordinary people, especially children and the vulnerable, are affected. Also, themes of resistance and the fight for justice in the midst of a 'dirty' war situation could be part of the story.
I'm sorry, I haven't actually read 'la guerra sucia' by Nathaniel Kirby. So I can't provide you with the full story directly. You might try looking for it in libraries, local bookstores or some reliable e - book platforms.
