Animal Heat by Susan G. Charles

Long ago, an ancient and powerful faction of shape shifters ruled and roamed the earth. Through systematic elimination, over the course of only a few generations, there are now only two left. Two sisters. So how did this happen? And so quickly?

Cats and dogs usually don’t mix. So what happens when a werewolf and a werecougar become mates, brought together by fate? Lots of excitement you can be sure :) 

Life happens to us all - and sometimes, in just the blink of an eye, it can go from normal and mundane to absolutely awful. And so it goes with this tale. One minute Lynda Seron, a shape shifter herself, was having a regular old ordinary day at home with her sister, Sonya, when something completely unexpected happened and turned both their lives around forever in a way neither of them would have ever guessed possible....

Werewolves & Shifters, sisters... a kidnapping, an unusual business deal and far out expectations to boot. Mix up a group of big cats and big dogs and find out what happens next! 

Can a wolf and a cougar find happiness together? Or will this new threat tear them apart?
