Finally wrote the beginning of Chapter 1 of "Grafted Vines" (the 3rd book). It took forever to figure out how I wanted to start that one and it just came to me yesterday. It's not very strong yet, but I'll revisit it later and work on that. Grafted Vines is going to be totally different from the other 3 books (at the point at least). I'm really looking forward to telling Dani and Zach's stories.
I also changed the way the entire series starts :) I think this works better
