Disowned Royal (Club Royal #4)
Elouise East

Oscar is living his dream. The owner of a beautiful two-storey building, which houses his cafe slash bookshop slash library, he is never happier than when he is working, which is all the time. When Prince Christian becomes a regular, Oscar tries to stop being so nervous around him, but the man is like a god. A haunted god, but a god, nonetheless. His scrutiny of the man means he notices when Christian nears breaking point, but he has no idea what to do about it. Does he really want to become part of it?
What or who can persuade Oscar that Christian needs his help, and his help alone, when the prince goes up against the people who wish to harm those they love?
This is an MM book containing BDSM scenes and D/s dynamics in all forms. It also has lots of loving, friendships, family drama and, of course, a HEA.
