I did not get the sense in the beginning of the book that Estrella and Vic would get together. They didn’t seem as though they were interested in each other. They appear to care only for her well-being because he was her alpha.
Estrella seem to be very insecure because she was a mix between a lion and a tiger. Plus, she was supposedly sterile. It started to get repetitive to me. We get it. She is 6 feet tall and looks slightly intimidating. But that was mentioned over and over.
When she finally decided to drive her self at Vic I thought she could have done it differently. Maybe her heat was making her crazy and weird.
