A thrilling sequel to A Good Girl's Guide to Murder by Holly Jackson. Set shortly after the events of the first novel, Pip Fitz-Amobi has sworn off investigating crimes. Instead, she and Ravi Singh have turned their previous case into a wildly successful true-crime podcast.

However, when Jamie Reynolds, the older brother of one of Pip's friends, suddenly disappears, the police are slow to act. Despite her promise to stay away from investigations, Pip is drawn back into detective work. As she follows a trail of hidden clues, secret relationships, and dangerous lies, she uncovers another dark conspiracy lurking beneath the surface of her seemingly peaceful town. The deeper she digs, the more she realizes that finding Jamie may put her own life—and the lives of those she loves—in grave danger.

Building on the strengths of the first book, Good Girl, Bad Blood delivers a more mature story, exploring the emotional consequences of solving crimes, the ethics of true-crime media, and the psychological toll that investigations can have on those involved.
