I had a book when I was a little girl that I absolutely loved. Now that I have 3 little nieces I'd love to get it for them to read but alas i can't remember the name. Its about 2 young kids a boy and a girl, that go to stay with their grandparents at a wildlife rescue center in south florida I can't remember if their parents passed away or are just away. They end up rescuing 2 baby florida panthers and hand raising them. One of the cubs ends up dying in the end. Anybody have any idea?
