Read this book back in the 2000s. I remember bits and pieces of it:
Triplet sisters (Hendersons I think), one has the ability to speak to animals, one can turn into an animal, panther or something, and the last can harness water power. All three have different hair colors. The father can turn into a bear and they have a tutor that speaks through a computer. They are hunted by this evil being that can teleport through mirrors. This entity can shapeshift I believe. That’s all I remember. Looking for the title if anyone knows this book!
