The Bleeding Heart: (Dragon Blood Chronicles Book 1) by S. E. Baker

Centuries before, a cult known as the Bleeding Heart reigned terror throughout the supernatural community. They hunted down their own kind and slaughtered them in the night. And now, they’re back. But this time, they’re hunting dragons.

Sasha Valentino is one of the last dragons left. When one of her friends is murdered, it’s up to her to find and protect the remaining dragons. But when a chance run-in with the cult leaves her almost powerless, how will she be able to protect the others and bring them to safety?
