Sorry, but I have no information regarding the author of this 'nada graphic novel'. It could be an up - and - coming author, or it could be someone who has worked mainly in a specific region or genre and is not widely known yet.
I'm not sure specifically what 'nada graphic novel' is about as it could be something relatively unknown or a very niche work. It might be about a unique story, perhaps a fictional adventure, or it could deal with personal and emotional themes in a graphic novel format.
Since I haven't read 'The Return' by Edith Tiempo, it's hard to say exactly. However, many works of literature deal with common themes such as love, identity, and the passage of time. It's possible that this story also explores these or related themes. For example, if the story is about a character returning to a place, themes of memory and change might be present. Or if there are relationships between characters, themes of loyalty and betrayal could be involved.
