Mockinjay finished with Katniss choosing Peeta and unable to forgive Gale who moves to district 2.
As a Gale shipper I didn't like this ending, but as J.K.Rowling tought us "the stories we love best do live in us forever", so, as I often do when I like a book or a movie I've tried to imagine how Katniss' story goes on.
Katniss has been living happily with Peeta for 2 years but she still think of Gale and, even if she can't admit it even to herself she misses him. Until one day she unexpectedly meets him in their old meeting point.
From this moment on Katniss' life will change completely. She will have to understand her real feelings, she will have to make choices and to face the consequences. And she will have to fight a new enemy who will put at risk all the things she, Gale and Peeta have fought for.
