Helen Langdon is a mother, an obsessive crafter, and a serial killer.
When sixteen-year-old Connor Marsh dies after stopping the medication that had kept him stable for two years, Helen learns about Serena Voss, a successful wellness coach who promises frightened and desperate people a better way to heal.
The deeper Helen looks, the worse it gets.
Serena has built a profitable business selling supplements, private coaching, retreats, and distrust of conventional medicine. Former clients have lost thousands of dollars, relationships have been destroyed, and vulnerable people have been encouraged to walk away from the very help they needed.
Helen has seen enough.
To get close to Serena, she joins her online program and signs up for one of her retreats. But spending time inside Serena's carefully constructed world proves more complicated than Helen expected. Serena is intelligent, convincing, and very good at making people feel understood, even when Helen knows exactly what she is doing.
Then Detective Rowan Pierce begins looking into Connor's death.
When Serena's sudden death gives him another reason to look closer, an old investigation is reopened, and the serial killer Rowan has been trying to understand is once again very much on his mind.
For Helen, that means finishing another journal, keeping her own involvement out of Rowan's investigation, and trying not to think too hard about how much more often he seems to be finding his way into her life.
The Bitter Cure is the second book in The Langdon Murders, a dark domestic thriller series following Helen Langdon as she balances family, murder, and a growing relationship with the detective investigating her crimes.
