12 Months to Live is a legal thriller by James Patterson and co-author Mike Lupica, published by Hachette Book Group. It is the first book in the Jane Smith Thriller series, released on September 25, 2023.

Tough-as-nails criminal defense attorney Jane Smith is hip-deep in the murder trial of the century — her charmless client may have committed several murders. On top of navigating the most challenging case of her career, Jane has recently fallen in love with a wonderful man and an equally wonderful rescue dog. But Jane is running out of time: she has just received a terminal diagnosis giving her twelve months to live — unless she's murdered before her expiration date.

Praised by Carl Hiaasen as a great team effort and by Louise Penny for getting "deep into the lives of strong women," Patterson and Lupica bring readers a fast-paced courtroom drama filled with sharp wit, high stakes, and an unforgettable protagonist. Available in hardcover, trade paperback, mass market paperback, ebook, and audiobook formats.
