I hope i chose the right subject site to post this but I need help to find a reading app for this story The Alpha Chose My Sistsr

It's about a girl named Zoe and on her 16th birthday instead of celebrating it turns into a funeral for sister, and the pack blames Zoe for her murder. Then Zoe discovered she has to wolf forms Iris and Feyra. The alpha heir Noah hates her even more when they find out they are fated mates. The reading app it's on is so expensive I was wondering if I could find a different app where I can watch videos for chapters or cheaper packages to buy.
