Not Quite Dead Yet is a #1 New York Times bestseller and the first adult novel by Holly Jackson, author of the bestselling A Good Girl's Guide to Murder series. This gripping thriller follows twenty-seven-year-old Margaret "Jet" Mason, who is living with her parents in Woodstock, Vermont when she is violently attacked on Halloween night and left with a fatal head injury. Doctors determine that within seven days, the trauma will trigger a deadly brain aneurysm. Rejecting a risky operation to guarantee herself a few more conscious days, Jet realizes she never thought she had enemies—but someone wants her dead.

With only one week left to live, Jet looks at everyone in a new light: her family, her former best friend turned sister-in-law, and her ex-boyfriend. Determined to finally finish something meaningful, she reconnects with childhood friend Billy, the only person willing to help her solve her own murder before time runs out. This propulsive countdown thriller features Jackson's signature plot twists, dark humor, and emotional depth, praised by critics as "unputdownable" and "a masterclass in thriller writing." The hardcover edition features a custom-stamped case, beautiful endpapers, and premium dust jacket. Published by Bantam, an imprint of Penguin Random House.
