Why Story Lines and Time Lines Are Never Meant To Be

Hello. As you can tell from the title, I'm having a little trouble. My timelines are out and I can't seem to fix it. Why is time not malleable? Would that be so hard?? Well, yes. Obviously. But still, help me out!
Why is it that when I read other books, they're perfect? I've only ever found one. Nora Roberts' The Hollow. Caleb's gran is 93 in this book, whereas in the first book Blood Brothers, she's 97. That's the only one I've ever found. Why can't mine work??

The Empire Of The Dragon Novel: 1

Hi, I'm Suzanne and I've been trying to write this novel for nearly ten years now. It's not going so well. Recently, it became my focus again and so here I am, hoping to find people who would read my novel. If you are one of these lovely people, please leave feedback (positive or negative, I don't mind) or questions so that I can get past this block and fulfill my dream of completing this novel.
(I assert my Intellectual Property Rights, so please don't use any of the information in this blog for yourselves. That would hurt both of us. )
Thank you,
Suzi
