Can recommend Subjugation, by James Galloway. Basically my favorite long slow-burn scifi books, about a young engineer with a knack for new tech a couple of years after Earth is found by a matriarchal psionic alien species. Absolutely fantastic worldbuilding, character development, and a huge focus on (hidden) politics. The first book is standalone, and about 1000+ pages iirc, but book 2 - 8+ is one continuous storyline following the character directly after, and it is amazing.
