“My name is Rylee and I am a Tracker.”

When children go missing, and the Humans have no leads, I'm the one they call. I am their last hope in bringing home the lost ones. I salvage what they cannot.

Underestimating demons is a bad idea, and it's a mistake that may cost me not only my own life, but the life of a missing child.

If I can swallow my pride, and allow Agent O'Shea to help me find a way to deal with the demon, we might be able to save the child.

With this salvage, it's a race against time, a test of trust, and a temptation that I'm doing my damnedest to ignore.

If only swallowing my pride was that easy.

Starring the irresistible, ass-kicking heroine Rylee Adamson, Immune is the first book in USA Today bestselling author Shannon Mayer’s sexy, exciting, and laugh-out-loud series, a dangerously addictive paranormal romance.
