Here’s the summary of Gathering Mist.

Secrets hide within the fog deep in the mossy forests of the Pacific Northwest in this ninth thrilling installment in award-winning author Margaret Mizushima’s Timber Creek K-9 mystery series.

Deputy Mattie Wray, formerly Mattie Cobb, is summoned to Washington’s Olympic peninsula for an urgent search and rescue mission to find a celebrity’s missing child. With only a week left before her wedding, Mattie is hesitant to leave Timber Creek, but her K-9 partner Robo’s tracking skills are needed.

Dense forest, chilling rain, and unfriendly locals hamper their efforts, and soon Mattie suspects something more sinister than a lost child is at play.  When one of the SAR dogs becomes ill, her fiancé, Cole Walker, suspects poison. Fearing for Mattie’s and Robo’s safety, Cole joins the search and rescue team as veterinary support.

Secrets that have lain hidden within the rugged terrain come to light, and when it is uncovered that the missing child was kidnapped, the search becomes a full-blown crime scene investigation, forcing Mattie, Robo, and Cole into a desperate search to find the missing child before it’s too late.
