She walked away from her life...
But what did she walk into?
Maddie Castle is about to find out.

A NEW Maddie Castle thriller from Wall Street Journal and USA Today bestselling author L.T. Ryan with C.R. Gray!

Maddie Castle has taken on plenty of tough cases as a private investigator, but nothing could prepare her for this. When a desperate mother begs Maddie to find her missing daughter, she expects to track down a runaway. Instead, she uncovers the dark heart of Willow Grove—a secluded community tucked deep in rural Pennsylvania.

Jasmine Armstrong had a bright future: a promising career, a loving family, and everything to live for. Then she vanished, leaving it all behind for Willow Grove, a place known for its self-sufficient lifestyle and promises of enlightenment. But Maddie quickly learns that Willow Grove’s surface charm hides chilling secrets. Beneath its idyllic facade lie whispers of disappearances, mysterious rituals, and a community bound by an unspoken allegiance to something—or someone—powerful.

The deeper Maddie digs, the more dangerous the search becomes. Jasmine isn’t missing, but she’s no longer the woman her family remembers. Something in Willow Grove has its claws in her, and getting her out might come at a deadly cost. With time running out, Maddie must decide how far she’s willing to go to uncover the truth—and if she’s prepared to face what she finds.

In the heart-stopping seventh installment of the Maddie Castle series, Maddie faces her most chilling case yet, where the line between salvation and destruction blurs. Perfect for fans of Lisa Gardner and Karin Slaughter, Beneath the Grove will leave you breathless to the very last page.
