#WritersCoffeeClub 19/9: Talk about how you've fixed a mistake in your work.
Writing is a constant learning process. Early in my novel-writing career (ca. 2003-08) I sold a series to Tor in the USA: it had errata—not surprising, it was longer than War and Peace!
In 2013, it got pocked up by Tor UK; I managed to convince my editor there to let me rework it from six slim fantasy-branded books into three fat technothrillers. Made over 3000 changes along the way. It was, indeed, a better version.
