When an assassin is framed for the murder of her partner, she risks the utopian society she protects to convince an unbelieving man from a rival family to take his rightful place as leader of the community, a feat that places her and the realm in jeopardy.

It's not clear what the causal relationship is; that is, how being framed for murder jeopardizes of the utopian community. Or why being framed compels her to nag the guy into acting like a mensch.

Also the plot seems to pivot on the guy, not the girl. She can only try to influence him; she can't MAKE him do what he needs to do. The biggest decision is his to make -- not hers. So who is the protagonist? And who is the antagonist, the common foe?
