In Into the Deep, book three in USA TODAY bestselling author Colleen Coble's Rock Harbor series, Bree's dog goes missing amid a murder investigation, and Bree pairs up with a former flame to search the wilderness for her missing dog and the truth someone is determined to keep buried.

Bree Nicholls has built a reputation for solving difficult cases alongside her highly trained search-and-rescue dog, Samson. Working the remote coastlines and forests surrounding Rock Harbor, the two have become an unstoppable team when it comes to finding the missing and uncovering long-buried truths.

But when a man working at a new local plant dies under suspicious circumstances, Bree's involvement in the investigation leads to a discovery she never expected--family she didn't know existed. Before she can make sense of the revelation, her world is thrown into chaos when Samson suddenly disappears. Determined to find her loyal partner, Bree follows a trail of clues that suggests the dognapping may be tied to the murder itself.

As the search leads deep into the wilderness of the Upper Peninsula, Park Ranger Kade Matthews joins the investigation, bringing his knowledge of the rugged terrain and a steady presence Bree quickly comes to rely on. Together they must navigate treacherous forests, dangerous secrets, and a killer determined to keep the truth buried--while racing against time to find Samson before it's too late.

Blending pulse-pounding suspense, emotional stakes, and grounded in faith, Into the Deep will keep you turning pages late into the night. Continue the adventure with Without a Trace, Beyond a Doubt, and Cry in the Night.
