This series is excellent.
It's best to read the series in order as although each couple have a story per book or per duet or trilogy, the enemy threat often runs for more than just their book and the couples relationships and friendship build through each book.
This is the conclusion to Z and Lilly's story.
The book picks up from the previous one with Z having been taken in by the cops.
The enemy threat is revealed and the situation with Sway is resolved, sort of.
The couples relationship is solid, they only have eyes for each other, no cheating..
That said there is ex drama and other woman drama as Z had been involved with many women before getting serious with Lilly.
No intimate scenes with anyone other than the Hero and heroine.
Secondary characters for future books in series and updates of previous characters in series plus exploration for another charter which could open up further books or a spin off series.
HEA but I'm sure we will see more in the rest of the series.
