But life comes with its own set of challenges. With all her attention focused on her career and her son's frightening illness, she's never had the chance to meet that special someone with whom to share her life.

Desperate to get to the bottom of it, Brynn is hurt when no one else seems to recognize the danger. Finally it becomes startlingly clear that something is amiss and lives are at stake. The truth may expose a threat far more sinister than her suspicions ever hinted. There's nothing a mother won't do for her family. Will her love be enough to neutralize the danger?
