The Immortal Profiler: The Witness Protocol

When death becomes visible, justice gets complicated.

Detective Marco Salazar died for two minutes on an operating table. He came back different. Plagued by skull-splitting pressure and cold sweats that intensify around death, the department calls it PTSD. Marco knows better.

Enter Valeria Navarro: brilliant profiler, impossible competence, and a past that stretches back two thousand years. An angel operative hunting a vigilante killer who is executing Madrid's criminals without trial, all while avoiding the attention of a far more dangerous threat who has been watching them both.

When Valeria chooses to reveal her true nature to Marco, she offers him a choice: walk away from the impossible, or become her partner in a shadow war that has existed since before Spain had a name.

The problem? Celestial law forbids attachments between operatives and mortals. Their partnership is an experiment the hierarchy expects to fail. And the threat closing in on them knows exactly how to exploit the bond growing between them.

Some partnerships are worth defying heaven for.

The Witness Protocol is the gripping first book in The Immortal Profiler series.
