Here's the story description:
Long ago, the Dragon Born were hailed as the most powerful mages in the world. Today, they are condemned as abominations and have been hunted to near extinction.
Sera Dering has spent her entire life hiding her forbidden magic from the supernatural council who would kill her for the crime of being born. After years of drifting, she’s finally found a new life working as a low-grade mercenary for San Francisco’s oldest monster cleanup guild. She’s safe—as long as she pretends to be human.
But a dark and mysterious power is taking control of mages’ minds, and Sera’s guild sends her in to investigate. To save her city from a magical apocalypse, she must work together with a sexy and deadly mage who represents the very council that sentenced the Dragon Born to death. And if he finds out what she is, she’ll be next…
Mercenary Magic is the first book in the Dragon Born Serafina urban fantasy series.
