McKettrick's Choice by Linda Lael Miller

Holt Mckettrick is about to get married to a mail-order bride when he receives word of John Cavanaugh's distress and his friend Gabe is in jail. Off he runs to solve the problems leaving his bride-to-be. Meanwhile down at the ranch, Lorelei Fellows is burning her wedding dress in defiance to her father and a groom who bedded the maid on the morn of the wedding. Holt and Lorelei are two fiery adults, knowing their own minds, stubborn and willful, a match made in heaven. Miller writes an exciting and page-turning tale of love and adventure in the early west.
