Amazing Gracie

This is a sequel to Saving Gracie, so if you didn't get to the end of the first, this will spoil some things for you. Like the first of the Gracie series, I have NO IDEA where it's going. I have a crazy idea about doing a Gracie trilogy, this being the middle, with each novel stand-alone, but with one continuous mystery that doesn't completely play out until the end of the third book. This means I'll need to delay publication on Saving Gracie, because we all know I'm incapable of planning ahead, and I'll have to drop back and take a chainsaw to Book 1. New readers - does this feel like a sequel? Or does it stand alone? I guess those are dumb questions since I'm just stringing scenes together, hoping a plot shows up. Thank you so much for reading! :)
