Freya Wallace delivers an outstanding start to a new crime thriller series with Hollow Ground, introducing readers to DI Jacob Knox in a gripping, atmospheric mystery set against the eerie backdrop of Dartmoor. 

From the very first page, this book pulled me in. The writing is incredibly well-crafted, making for an easy yet immersive read. The story flows seamlessly, striking the perfect balance between suspense, character depth, and investigative detail. Knox is a compelling lead—his past hardships and the personal issues he is currently dealing with add layers to his character, making him instantly intriguing. I love that this is the first book in a series because I’m already eager to follow his journey and see how he develops in future books. 

The mystery at the heart of Hollow Ground is expertly woven, keeping me guessing until the very end. Sophie Parsons’ disappearance, which occurs six months after another lone woman, Rachel, vanished while walking Dartmoor, is more than just a missing person case; it’s a tangle of secrets, relationships, and the ever-present whispers of Dartmoor’s chilling legends. There are similarities between both cases—including DI Knox—which raises the question: could they be linked? Wallace does a fantastic job blending the psychological with the procedural, making every revelation feel both shocking and completely plausible. 

One of the standout aspects of the book is the investigative team. The cast of officers involved in the case is just right—not too many to be overwhelming, but enough to feel authentic. Each officer is well-drawn, with enough detail to make them feel distinct and real. Their interactions and teamwork added to the novel’s realism and kept me fully engaged. 

I also loved the setting. The stark, rugged beauty of Dartmoor is brought to life in a way that feels almost cinematic, adding an extra layer of atmosphere to the novel. The descriptions of DI Knox’s early morning walks on the beach were a particular highlight—such a brilliant touch that made his character feel even more grounded and relatable. 

With a perfectly paced plot, a deeply satisfying conclusion, and an exciting protagonist, Hollow Ground is a stellar debut for DI Jacob Knox. I can’t wait to see where this series goes next!
