looking for slow cooker recipe books

Hi, I am looking for a book that has recipes for slow cookers.  I can't seem to find one for weight loss surgery people.  I found some but they have so much calories and fat.  Does anyone know of any cookbooks out there for slow cookers?

thanks
Barb

I have one called Fix It And Forget Light....I love it!
