Well, like Destiny you managed to deliver a hard sci-fi story (by Trek standards, edging out Destiny with catoms and relativity by several orders), excellent characterization and great yarn of a plot.
I don't want to post spoilers yet lest the thread jump on me but there are some great comic moments in there.
In terms of style it seems very much an evolution of your style in The Buried Age
, better this time with experience and a freer hand to not have to neatly bundle everything up at the end. Several character choices seem similar to The Buried Age,
you seem to have a preference with the styles of aliens you create. Similar choices manifest themselves.
