The general's mate- ACOTAR

After the war with Hybern, Velaris was in the process of rebuilding and Araminta was no exception. Losing both her parents in the attack on Velaris, Araminta is forced to move on alone being an only child and a new orphan.
Just when she feels most alone her High Lady offers her an escape. She tells her about an art class that she offering for young people impacted by the war and attack on Velaris and she is invited to join a class. At first she is hesitant, she's never been much of a painter, but something tells her she should go so she accepts Feyre's offer.
Halfway through the class, Feyre's mate, Rhys, the High Lord of the Night Court, and a male she had seen while out and about the city walk in. His dark shoulder length hair and tattoos were particularly visible in the gallery's faelights as well as the veins and colors of his giant wings. As if he had known she was staring, he stares back intently for a few moments, before breaking the stare to converse with Rhys.
After the class is finished I am the last in the gallery so I walk up to Feyre to thank her for the invitation, and she introduces me to Rhys and the male from earlier.
"Hello I'm Araminta," I introduce myself quietly to stranger.
"Hello Araminta, I'm Cassian." He replies in a deep rich voice.
