I love dark romance and even some taboo tropes, but this one was just over the top and gross. 
I made it to the end and I get why people say to keep going vs DNF… but finding out the characters weren’t actually related wasn’t even helpful when she was 1. upset about that fact (wtf) and 2. the dad raised her from the time she was 2 so still crosses those lines without any good reason. The flashbacks make the whole “but they were stranded in the wild” arguments invalid.. they were crossing the line well before they headed to Alaska. 
I wish I could unread this.
