Ruby was blackmailed into helping Luke save elskov from an arms deal. Luke was the leader of black nights, whom you met in the first book (each is a standalone) his under cover princess, Ruby is the step daughter of a crime boss and the black knights decide to use her.
There is a lot of chemistry, which of course Luke and Ruby try to fight, intrigue, capers and suspense in this story. Avery Flynn keeps you guessing and wanting more. This was another great read . Cannot wait for the next book in this serious.
