The main character is Mackenzie Allen Phillips, a father of five, called “Mack” by his family and friends.

Four years prior to the main events of the story, Mack takes three (of his five) children on a camping trip to Wallowa Lake near Joseph, Oregon stopping at Multnomah Falls on the way. Two of his children are playing in a canoe when it flips and almost drowns Mack’s son. Mack is able to save his son by rushing to the water and freeing him from the canoe’s webbing, but unintentionally leaves his youngest daughter Missy alone at their campsite.

After Mack returns, he sees that Missy is missing. The police are called, and the family discovers that Missy has been abducted and murdered by a serial killer known as the “Little Ladykiller”. The police find an abandoned shack in the woods where Missy was taken. Her bloodied clothing is found but her body is not located. Mack’s life sinks into what he calls “The Great Sadness”.
