The novel, published in 2007, is a work of fiction that explores themes of faith, forgiveness, and the nature of God through the story of a man named Mack who encounters a mysterious figure in a shack after the tragic loss of his daughter. The film adaptation, released in 2017, follows the same premise and themes as the book.

"The Shack," based on William P. Young's novel, sparked controversy primarily due to its unconventional portrayal of God and theological themes. Critics argued that its depiction of the Trinity—featuring God as a black woman, Jesus as a Middle-Eastern man, and the Holy Spirit as an Asian woman—challenges traditional Christian views. Additionally, some religious groups felt it presented a too-lenient view of sin and suffering, while others praised it for addressing deep questions about faith, forgiveness, and the nature of God. This polarized reactions among audiences and religious leaders.
