It's a shame that quality of the writing seems to be a secondary factor in deciding who gets to write tie-in fiction. Even more of a shame that how well you get along with somebody factors into that decision.
On the other hand, we have David Mack/Wardlimore/DRGIII/Kirsten Beyer/Greg Cox writing really excellent Trek fiction, so at least some consideration is given to quality. Just remove MaM from and add KRAD to that mix, and we're cooking!
The wife and I love KRAD's books (her favourite is Diplomatic Implausibility
, mine is The Art of the Impossible
), and now we'll always be maudlin when re-reading one of his great Trek works.
