"As his mind finally understood what was in front of him, he fell backward in terror. Bones, partially buried in the mud... a skeleton."

In the dark forests of Sandviken, Sweden, a horrific find is made that resonates through the lives of four families, bound together by memories of joyful summer vacations, but confronted with a dark secret they had long thought was a remnant of the past.

For more than thirty years, a serial killer has been living among them, preying on innocent young girls and using them for his perverted pleasures.

The investigation is going slow and the inspectors who are put on the case are not only confronted with a cunning, calculated and ruthless murderer, but are faced with their own personal demons.

It is only a matter of time before he strikes again.
Will they be able to stop him this time?
And at what price?
