Fantasy fiction, a girl mated to alpha, finds she has powers with others like her who she is chosen to lead into a war against wolves from her sister she didnt know about

Hello im new to this so sorry if this isnt correct lol. So i started reading a book on one of my many apps(dreame, anystories, wattspad, radish, novel now list goes on) round 2020/2021 but still cant find it. Overall i dont remember the characters names which is sad and i thought the title was "true queen" or "the luna queen", but the descriptions didnt match on google. So i cant remember if the girl in the story was a wolf but she was mated to a alpha, after mating/marked a guy comes to her and tells her she has to leave but didnt say why, he comes to get her a couple days later in the process of leaving her mate notices and goes after her and saves her successfully, so the guy tries again with success they travelgo into this other world/dimension. While her stay there she finds out she is gifted and there are others like her and she was chosen to lead this group(i think she becomes there queen). With her stay she taps into her gifts/talents/powers and then is told that a war will start soon against the wolves once(either all the leaves have fallen or once all the leave change from green to brown) and the person of the war is her sister she didnt know she had(cant remember if they were twins). Now she has been gone 6/7 months and returns to her pack where she tells her mate whats to come and her powers. This was as far as i got if this sounds familiar to anyone please help. Thanks much.
