Hi there. So I'm revising a book I wrote and few agents I pitched to at a conference said I could send them the first chapters when I'm done revising. One agent said because my main character is 13 and that is right at the start of YA it probably should be a MG book. I'm hoping to make this into series and the content for this book might be MG but the other planned books would absolutely be YA.
Do you think it's ok to have the first book be MG and then plan for the sequels to be YA or all the books should be YA? Also I've heard a book should be classified as middle grade if the romance is very innocent (crushes, first kiss). That's the type of romance for my MC in this book. If I did go with my book being YA could I do that when the very innocent romance is the only kind in the book?
I would appreciate any advice.
