It's difficult to assign a specific grade to 'Ella Enchanted' as it can be enjoyed by readers of various ages. Generally, it's suitable for middle-grade readers and above.
The book 'Just Ella' is definitely fiction. It weaves a tale that is purely from the author's imagination, not based on real-life facts or experiences.
It could be aimed at young adults. Young adults often face various challenges in life such as self - identity and relationships, and a story like this where Ella is 'coming clean' might resonate with them as they also go through similar processes of self - exploration.
I'm not sure specifically as I haven't read this 'Coming Clean by Ella'. It could potentially be about Ella's journey of self - discovery or her coming to terms with something important in her life.
Begin by researching the author, Ella Frank. Understanding her writing style and previous works can give you a better context for her graphic novel. You could also start with the first few pages. See if the art style grabs your attention right away. Sometimes, the initial pages set the tone for the whole story. If it has a prologue, that's a great place to start too as it often gives some background information that will be useful as you read further into the graphic novel.
I'm sorry, I don't have specific information about the love story of Ella Pangilinan and Enrique Miranda. There could be many couples with these names, but without more context, it's difficult to detail their love story.
I don't know of any evidence that Ella Frank has tried a graphic novel. Ella Frank may be known more for other types of works, and without clear announcements or works in the public domain related to graphic novels by her, it's hard to say for sure. However, in the creative world, many artists like to experiment with different mediums, so it's not entirely out of the question.
