Preorders Are Now Open: Fighting Edge by Margaret Mizushima

The eleventh book in the Timber Creek K-9 Mystery series is coming this fall, and preorders are open now. Fighting Edge by Margaret Mizushima is scheduled for publication on September 8, 2026, from Crooked Lane Books.

In Fighting Edge, a routine welfare check becomes a nightmare when Deputy Mattie Walker arrives to find a young mother dead and a hysterical toddler, possibly the only witness to a terrible crime. Before the investigative team can begin piecing together what happened, a traffic stop brings a second threat to Timber Creek. A sweep of the car with K-9 partner Robo reveals drugs and the signs of suspected human trafficking, and a teenage passenger frozen with fear. What begins as a speeding citation opens into an investigation that reaches far beyond the borders of this mountain community.

Ten books in, Margaret Mizushima only gets better. The Denver Post has called her “one of the West’s finest contemporary mystery writers,” and the early praise for Fighting Edge confirms that distinction.

Scott Graham, National Outdoor Book Award-winning author, writes: “A haunting tale of tribulation turned to triumph that only Margaret Mizushima could create. Mizushima masterfully mines Mattie Walker’s own troubled past when Mattie and her crack K-9 Robo confront the worst the world has to offer — the brutalization of throwaway children — making for a poignant and compelling tale with a fiery finish.”
