Wings of Exile by JD Monroe

A woman who has lost too much.
“Call this number before you call the police.”
Natalie Thomas never thought she would have to follow the cryptic instructions, but she’s forced to obey when her best friend Thea goes missing. Her day only gets weirder as she files a police report, meets Thea’s unreasonably gorgeous “cousin,” and gets attacked by a dragon in her living room.
A dragon determined to avoid love.
Since his heart was shattered by his one true love, Erevan Skyblaze has filled his days with work and his evenings with meaningless flings. But when he is called to investigate the disappearance of a young dragon woman, he meets the beguiling and stubborn Natalie Thomas. Not only does she defy his dragon compulsion, she doesn’t seem to know that she’s not entirely human.
They’ll have to trust each other, or they could lose everything.
Together, Erevan and Natalie begin an investigation that veers into dangerous territory as they discover the resurgence of a dragon-slaying cult. Long thought dead, these mysterious enemies pose a grave threat to the dragon world. And the fiery attraction between Erevan and Natalie may prove to be the one thing that can protect them.
