Status Updates From Alpha Trine (The Valespian ...

So I didn't get how their relationship just did a whole 180. Suddenly they're having sex and decide they stop disliking each other from one second to the next...? dnf-ing this now... ^^

This book is super confusing. They just suddenly go from hating/not trusting each other to some weird kind of insta love and trust and there are too many species and races for me to keep track of especially since most of them just get name-dropped in their without it having any discernable benefit for/impact on the story? Also: it's space, why does a non-human race believe in ancient Greek gods?
