The Scouts by Kasia Bacon

Soldiers. Lovers. Soulmates.

Lochan and Ervyn—an assassin and a sharpshooter—remain in service to the Queen as part of an elite reconnaissance unit.
The Scouts are ghostlike. Elusive. Deadly.
They strike at enemies of the Crown without mercy. They get the job done, leaving no loose ends or witnesses. When Magic Supremacists threaten the safety of Elven Country, they do their duty—whatever it takes.
Lochan and Ervyn belong to each other, but will serving together as comrades-in-arms strengthen their bond as lovers or tear them apart?

The Scouts is the third book in the Order Series. In this volume, Ervyn loses control, Lochan stops fighting his feelings and Verhan… well, remains Verhan.
