FYI Scalzi is not the only author with Hugos for writing books and writing about books. Frederick Pohl got the second one in 2010.

If you will go by the order shown there is a swap - "Brothers in Arms" comes before "Mirror Dance". That’s a part of the series where it would be confusing to go out of order.

Are there any news about an audiobook? I tend to continue series in the format I read it first, and I found the Wilde Investigations via audiobooks. So I’m wondering if I should wait just a little bit longer or turn to (already purchased) ebook.

Ina suprising move there is a brand new Vanyel short story (Uncivil Blood) in the latest Tales of Valdemar collection.
