Bryan, the release you received should say which books you are in. I'll have to go and have a quick check back through my list.....
Back again. No, you definitely misread it. You are in at least four books (didn't check thoroughly), but they are all later ones. (Sorry.)
If you've got a copy of the release form, the Appendix has the list of books you're in (and the number they are) right at the back.
Having said that, PLEASE jump in when I post about "gap filling" for the books slated for publication before that. There are LOTS of gaps, in Book 2 as well. We used about four gap-fillers for the first book, and I think there are at least that many in Book 2. I'll be posting opportunities to submit for those vacant topics very soon.
