To save a child, he has to risk his own life.

When a minivan slides off the road into an icy lake, Officer Samuel Miller narrowly rescues a woman and child from certain death. Only, Rachel Harding insists the crash is no accident — it’s eerily similar to how her sister and brother-in-law recently died. As the unexplained attacks escalate, Samuel is determined to protect Rachel and her orphaned niece at all costs. But when they make a shocking discovery, their investigation becomes even more dangerous, and survival may be impossible.
