Decades after a brutal childhood trauma, a famous novelist finds his life shattered once again, in this unsettling psychological mystery thriller.

After years of turmoil, Brooks Anderson is sober and has a stable life with his wife and two kids. He should be enjoying life, but the persistent nightmares and sleepwalking tell a different story.

As hard as he's tried, Brooks can't run away from the defining event of his life: the senseless murders of his mother and brother during a vacation in Montauk. An eight-year-old Brooks was the sole survivor of the carnage, which left him in a catatonic state. He buried his pain and eventually overcame his demons. Or so he believed.

Now an unscrupulous journalist is threatening to write about the deaths. Fearful that the truth will be twisted to suit sordid ends, Brooks decides to write his own book, despite the grave misgivings of his agent, wife, and father.

However, when the journalist is brutally killed, Brooks finds himself in the authorities' crosshairs. To prove his innocence and exorcise the past, he digs deeper into his psyche and that fateful summer. His relentless pursuit of the truth soon leads Brooks down a slippery slope that challenges everything-and brings him face-to-face with the real monster of Montauk . .
