It's here -- King's Gambit

Calle had never been important to others. Maybe that was why he fell for Mosca, the most unobtainable person he’d ever met. When Mosca chose him to be his personal guard he should have suspected something was off. No one chose him for anything. But this time was different. Very different.

Mosca’s world was a dangerous one, full of deceit and treachery. He told Calle he trusted him and made Calle his personal guard. But living one step away from betrayal and falling in love with the man changed both of their lives. For good.
