Right now with the YA book, I'm waiting on the beta readers, and (since I've got the cover done) there's not much for me to do until they finish up.
I don't know when they'll finish, though, and there's some other stuff going on that's interrupting my time. But I've got 30 chapters of Trials written, and they're rough drafts, so I think what I'll do is just start editing the earlier chapters. I actually kind of need to reacquaint myself with that book, since it's been a while, so this will hopefully kill two birds with one stone.
