It's 1912 and statehood has come to Arizona. Former stagecoach driver, Joe "Whip" Adams, now a railroad detective, along with his Cocopah wife and son are part of an inauguration procession to the State capitol. A survivor of stagecoach massacres and train robberies, Joe's adventures come from journals he began in 1859. Transcribed by modern day descendent, Rachel Adams, the journals were discovered hidden in the false bottom of a steamer trunk, revealing family members she never knew existed. The Highway through Mohawk is the final book in a trilogy, bringing first hand accounts of life and death at a roadside stop 50 miles east of Yuma. Included are stories of World War I and II, Japanese internment camps, the Korean War and the coming of an Interstate super highway that will doom Mohawk. The Highway through Mohawk introduces Rachel Adams to her grandmother, Constance who writes the family's final chapter. The person who is in the middle of Mohawk's end turns out to be Rachel's late father. The clash of events finally explains why the journals were hidden and kept secret.
