Hunted By Wraith by Hope Cretney

When two powers of the underworld collide, they walk a dangerous line between vengeance and lust.

She is the Wraith—a relentless force of vengeance, hunting in the shadows with a single goal: to destroy the people who murdered her father. No distractions. No mercy. But her mission leads her directly into the path of a powerful criminal syndicate team, whose pursuit could threaten to crash into her own.
When their enemies turn out to be one and the same, the only way forward may be to work together.

Trust is dangerous. Falling for them could be catastrophic. They may share a common enemy, but in the end, their paths are different. No one signed up for this, but will they emerge victorious—or will someone end up losing.
