Hi, I have a novel that is Adventure, but I'm not sure if it should be YA or A. It's based on a 14 year old boy befriending a 15 year old Sasquatch. It is also told from four points of view (2 adults and two teenagers), alternating between chapters. The issue is that my book is in 2 parts with four years between. So at the end of the story the boys are 18 and 19. I also end the story with an obvious sequel ending. My future book takes place again 4 years in the future.
So my question is do I classify it as Adult since part 2 and my future books are based on the same characters as adults?
Thanks for any help
