Branded by Fire (Psy/Changeling‪)‬

When a brilliant young researcher is kidnapped, DarkRiver sentinel Mercy, a cat, and SnowDancer lieutenant Riley, a wolf, must work together to track the young man—before his shadowy captors decide he's no longer useful. Along the way, the two dominants may find that submitting to one another uncovers not just a deadly conspiracy, but a passion so raw that it'll leave them both branded by fire.
