In seven days, Jet Mason will be dead.

Jet is the daughter of one of the wealthiest families in Woodstock, Vermont. Twenty-seven years old and back home, she’s still waiting for her life to begin. I’ll do it later, she always says. She has time.

Until Halloween night, when she is violently attacked by an unseen intruder, suffering a catastrophic head injury. Doctors are certain that within a week, the injury will trigger a fatal aneurysm. To her parents’ dismay, Jet rejects an extremely risky operation in order to guarantee herself at least a few more days.

Jet never thought of herself as having enemies. But now, in the one week she has left, she looks at everyone in a new light: her family, her former best friend turned sister-in-law, her ex-boyfriend.

As her condition deteriorates, she reconnects with her childhood friend Billy, the only one willing to help her. With Billy at her side, she’s absolutely determined to finally finish something:

Jet is going to solve her own murder.
