They'd saved his life, but at what cost?

When an accident left him near death, the PAX League saved Riley Tremaine's life… by transforming him into a terrorism-fighting superagent with a special gift for sight. To protect the future, Riley cut all ties with his past– and said goodbye to the woman he loved, anthropologist Nina Phillips.

A year later, when Nina called him in distress, the secret that destroyed their relationship could be the only thing to save her from the frightening plot of a madman. In a race to recover a missing artifact, Riley and Nina would have to believe the unbelievable and trust in a love they'd thought lost forever– or the world would pay the ultimate price.
