In which order should I best read The Edda of Burdens-series? Publication date or chronologically plot wise?

So, should I read By The Mountain of Blood before All The Windwracked Stars, or after? 

I'm not familiar with that particular series but I think it's best to read any series in the publication order.  I like to take that tour of discovery as it was created.

There is also the idea that an author hones his/her craft over time and I'd rather read the weaker/less mature works first and move on to what should be better written books.  In some cases an author will re-visit a series after many years and insert a new book into the middle of the run.  You could end up reading a book written written 10 years after the previous volume then go back to the next book in the series from a decade before.

Edda of Burdens is a trilogy with only 3 years between the first and last book so it may not be a big deal.

Just my 2 cents.
