Twisted Tales Let It Go by Jen Calonita

In this retelling of Frozen, Elsa grew up as an only child while Anna grew up adopted to her knowledge unknowing her rarely visiting aunt is actually the queen and her mum!

When their parents die, Elsa discovers the secret with Olaf's help and sets off to find Anna while Anna feels drawn to Arandelle as she always has and so plots to venture there with the help of Kristoff and Sven.

Can the girls find and heal their lost sisterly relationship?

This was literally a Frozen retelling through pieces of the film being moved around like a jigsaw with alterations added throughout and you know what, it worked so well I prefer this version I think!
