I am writing a manuscript that starts with the MC at 7 yearrs old. He soon turns 9, then 11, then 15, and so on. The novel ends with him in his mid-20s. The voice starts out young and I want to pitch it as MG, but at the very end of the book, he does sound more mature (with slight, gradual changes throughout as the story moves along). Is it wrong to label this as MG? Should I make the voice mature from the beginning to avoid the changes at all? Am I doing something wrong?? I’m so confused! Help!!
