Apparently not.
She wrote Pepper this morning and said she needed the title of the sequel so that she could issue our contract to us. And she hasn't had the book yet. In fact, we haven't talked to her about it since March when we agreed to have it to her at the end of May. So it looks like the series is definitely a go! She is also already coordinating the cover art for the sequel, so our worrying looks like it was pointless, lol.
