The Coltons Of Grave Gulch runs twelve books following different members of the Colton family as they face danger in their small town. From Colton’s Dangerous Liaison through Proving Colton’s Innocence, each entry pairs a family member with a love interest while contributing to the town’s larger mystery.
All twelve books were published in 2021, making this one of the largest single-year Colton sub-series. The multi-author format means each book brings a different voice while maintaining the family connections.
