Missing Sister by Joshilyn Jackson is an exceptional, very highly recommended domestic thriller. This tension-packed, well-written Southern character-driven drama following the complex relationship between sisters, as well as revenge. Any novel by Joshilyn Jackson is a novel that should be read immediately. This is one of the best of 2026. 

Penny Albright is a rookie cop in Kennesaw, Georgia, whose deceased twin, Nix, is always on her mind. The two grew up with the close connection twins and sisters share. Second guessing actions she could have taken, Penny continues to feel guilty after Nix died from an overdose five years earlier.  So when she is called to her first first murder scene, Penny is shocked to realize she recognizes the victim, Danny Bowery. He is one of the three men who assaulted Nix, sending her into the downward spiral which ended in her death. 

When Penny is tasked with cordoning off the area, she smells something and goes off to investigate. In an alley she finds a woman, drenched in blood, vaping, with a bloody box cutter nearby.  She calls herself Thalia Grey and intimates that Bowery's death is related to something much larger. Something that involves sisters.  Something that is not done, that doesn't involve cops. Penny feels an inexplicable connection with Thalia, tells her to run and lets her go. She bags the box cutter and says nothing, later hiding it. Circumstances spiral out of control, leaving Penny willing to sacrifice her career to find out who Thalia really is and, perhaps, help her.

As expected, the writing is excellent, the pace is fast, and the tension rises with every page in this un-put-downable thriller following Penny investigating on her own. Penny also knows that Xav Castillo, another one of the three men involved in Nix’s death, has also been murdered recently and questions if his death is connected to Bowery's death. With Thalia's comment that it was about sisters on the forefront of her mind, Penny wonders if it is about revenge for Nix or a sister of Thalia. Complicating matters are family issues, with her niece Shadow, who has been suspended from school for hacking, and her wandering, influencer brother, Shadow’s father, Gand, arriving. 

Penny is a complex, fully-realized character with both strengths and weaknesses. Personally, I thought she was a great, well-developed character. Jackson captured the special connection that sisters, especially twins, can have, including the talking to/thinking about the missing sister after one passes away. Thalia along with the supporting characters also come to life under Jackson masterful writing. 

All of the twists and surprises in the plot are unpredictable while adding to the anxiety and fear over what could happen next. Perhaps some suspension of disbelief is required, but I willingly, easily did so as the tension increased along with the questions and danger. My complete attention was held right up to the surprising final denouement. I sincerely hope this is the start of a new series featuring Penny Albright.

Missing Sister is an excellent choice for everyone who enjoys character-driven domestic thrillers. Thanks to William Morrow for providing me with an advance reader's copy via NetGalley. My review is voluntary and expresses my honest opinion.
