Ferocity by TL Reeve

The bravest never go looking for trouble
Hearts and Paws Sanctuary has been in Scarlett Leon’s family for generations. When her grandfather wasn’t running the day to day activities, her father had been. Then, ten years ago, in a tragic accident, her family perished leaving Maisie and Scarlett to run the day to day operations and care for their residents. Together they have saved countless injured and malnourished animals and domesticated big cats. However, two months ago, her sister set out to destroy their haven.
Well, not on Scarlett’s watch.
With the help of Edward (Ed for short), Dave, and Kenny, she’ll do whatever it takes to keep their animals safe. Scarlett might have been the ugly, anti-social daughter no one talked about, but she won’t let her legacy go waste. Her ancestors built Hearts and Paws Sanctuary for a reason, and she’ll do whatever it takes to make sure her sister doesn’t turn it into a wasteland.
Maisie might be the King of the Leon family, but come hell or high water, Scarlett will be the Queen of their legacy.
