I've taken my wife's advice to not worry about re-write of "Jorath's Quest", but to press on an write new books in the Circle College framework ("The Apprentice's Talent" is first) I think I'll not worry too much about edit of TAT till the next few are done in case I need to go back and change something. Though they are mostly standalone. The only "over arching" plot item is really Earth's Starship which is entirely minor and unimportant in all but one of the envisaged books. So eventual reading order will not be absolutely critical, though Maisie gets 3 "Talent" books.
So yesterday I created plot outline, list of about 26 "events" etc. What doesn't fit in about same length of book for "The Journeyman's Talent" will go in other later books.
