Thank you for the cover pictures. They both fit Elijah, the boy next door, and Kage, the international spy and assassin. They are both Hot! That would explain the quick sexual attraction of the two, however, the way you wrote about that attraction made it seem to be likely more. I suspect that we may find out later that they are true, destined mates. They are related to animal shifter who have this kind of bond. The fact Kage's Fae boss referred to Elijah as Kage's toy would indicate he senses at least the attraction between the two.
Kage's surveillance of Elijah at work and tracking him is also interesting. He needs to find out more, and is also staying very close to Elijah to find out more information. Is this only to do his job, or a way of getting closer to Elijah? You have written a very intriguing chapter, and no cliffhanger.
Anyone for a game of cat and mouse? It seems the story might have several players in the game. Guess which parts Kage and Elijah will play!
