The Coltons of Red Ridge brings the Colton family to South Dakota, where the local K-9 police unit gives the series its distinctive feature. Eleven books follow family members through romances complicated by a serial killer targeting the community.
Published primarily in 2018 with one later entry in 2022, the series uses the K-9 element to add another layer to the standard Colton formula — the dogs are working characters, not just props.
