While most of the details (including the title) will have to wait until an official announcement is made (which I'm told will be sometime next month), I *have* been authorized to release a few tidbits concerning my now-officially-approved upcoming Star Wars novel.
First, it will be be set in the classic movie era.
Second, it will be an Ocean's Eleven-type heist caper.
And third, it will star everyone's favorite smuggler, Han Solo.
Sounds great! I like the idea of a non-"epic" heist type novel set in the Star Wars universe. With any luck, it'll exclude any Sith lords/Death Stars/space battles/etc. Also, here's hoping it won't include Thrawn or Mara; as much as I love those characters and as much of a Zahn fan as I am, nevertheless I feel that he tends to go overboard on including them wherever possible.
