I'd read almost every book by Jennifer Chiaverini, I love them, and the last ones are more about history and Civil War, not too much about quilts (less interesting for me)
About the twins, are Sarah's babys: a girl and a boy. In the Wedding quilt (happening twenty years from now) Caroline (the girl) is getting married.
I'd read also some by Marie Bostwick too, and actually I'm reading one right now. I like it!
Thank yo for all this information, I'll check some authors.
have a nice day!
