carrieg is right on the first book's title. There is usually a listing of the books inside the front cover and before the title page. There are at least 15 out, I think. The new one would make 16. There are also 4 or 5 quilt pattern books based on the novels.
I am a retired church librarian, and love to read. So when I start a series, I can't quit until I've read them all, then wait impatiently for the next one.
