SOLVED. YA Fantasy. Two girls named Cat and Kat, [s]

[Lucy]

The book had 2 girls named Cat and Kat. There parents had just got married and I don't think the girls got along. They moved to a new house in a new town. I remember one of the girls bought a scissor charm. It had a magic or fantasy element, I think revolving around the game. The cover was red. I read it between 2011 and 2016 so it must have been published before then.
