A gripping psychological mystery thriller by Holly Jackson and her acclaimed adult fiction debut. The novel follows Jet Mason, a 27-year-old woman from one of the wealthiest families in Woodstock, Vermont. After a brutal Halloween-night attack leaves her with a catastrophic brain injury, doctors tell her she has only seven days to live before a fatal aneurysm is expected to occur.

Instead of undergoing an extremely risky operation with uncertain odds, Jet decides to spend her remaining week solving the mystery of who tried to kill her. With the help of her loyal childhood friend Billy, she investigates a growing list of suspects—including members of her own family, her ex-boyfriend, and people from her past. As the countdown to her death continues, every revelation exposes deeper secrets, lies, and betrayals.

Combining a race-against-time premise with Holly Jackson's signature twists, dark humor, and emotional storytelling, Not Quite Dead Yet explores themes of mortality, family dysfunction, regret, redemption, and the value of truly living. It became an international bestseller and won the 2025 Goodreads Choice Award for Readers' Favorite Mystery & Thriller.
