Did Thrawn write anything prior between the Thrawn trilogy and Hand of Thrawn? I should ask this question in the recommendations thread, but if so are they any good? His writing seem to have gone from good to dull pretty in a fairly short period of time.
He wrote a number of short stories during the interim.

I haven’t gotten around to reading many of them yet. Of the ones I did read, some – like “Hammertong” or “Side Trip” – were good, while others – like “Sleight of Hand” – were meh.
