My Italian readers had to wait two years for the second adventure of Asteria: Minos was published in August 2014, Great Khan in July 2016.
The foreword to the English language edition explains a bit of the background on that hiatus.

And my English readers are getting the Second Asteria Adventure, Asteria in the Court of the Great Khan barely one week after the first, both on Gumroad (for those that do not like Amazon, or prefer a different file format) and on Amazon.
Nice and smooth¹.

As I have mentioned elsewhere, and quite often, while Aculeo & Amunet is a historical fantasy, the stories taking place in the interstices of history, and I try therefore to keep my historical facts straight, Asteria is a peplum, or a sword & sandal if you prefer, and there is no attempt at historical accuracy in the stories.
Just like the old Maciste or Hercules movies, the historical background is an excuse to cause mayhem and to provide a change of costumes and scenes from one story to the next.

I did a modicum of research on Mongolian names and Mongolian folklore for the background of this story, but I played fast and loose with those, too.

I hope you will enjoy the story anyway.
