I say writing instead of revision because I will be rewriting most of BIV and changing much of the plot line. There's going to be some crazy stuff that our heroine Sabra runs into, stuff that will involve some ancient Liberan history and technology.
Right now my current order of projects is BIV of LI, then Book 3 of The Legend of Draconite. B3 of LoD is long due, and I'm excited to make some heavy revision on it, especially in regards to Sabra. In the original versions of LOD, I didn't mention Sabra was a witch until B5 of LoD, but in the new version of Book 3: E'lsra, Sabra will begin formal magic training with her bodyguard and mentor, the Crin Warlock Eveningstar. It makes more sense that way.
