I am on the third day of Tourbillon
revisions, and have just finished a close read through the end of chapter four of the draft. All I'm doing right now is getting way down to the line level, editing as I go. Once I've gone through the book this way, and have it firmly in my head once more, I'll go back through seeking larger scale cuts and changes. The draft is about 35% over wordcount, so a great deal of cutting and tightening will be in order.
I should have this pass done before the end of March.
