When Jet Mason is violently attacked on Halloween night, she barely survives but has a ticking time bomb in her brain that will kill her within a week.  Rather than risking a surgery she likely wouldn’t survive anyway, she decides to spend her remaining time trying to find out who attacked her and why.  Staying with her childhood best friend, she starts investigating, uncovering family secrets involving her parents, her brother and sister-in-law, and her long-dead sister.  When she dies without learning the truth, her friend puts the final pieces together to find out the truth.

Winner of the 2025 Goodreads Choice Award for Favorite Mystery and Thriller, Holly Jackson’s Not Quite Dead Yet puts a unique spin on the genre in her first novel intended for adults.  While searching for her “killer” is the main motivation of the Jet character, she learns more about herself during the investigation than she bargained for, finding how the choices she’s made, in the wake of her sister’s death, led her to where she is in the present and the regrets she will have now that time is no longer an unlimited resource.  I enjoyed this enough to keep an eye on Jackson’s back catalog and for any future output.
