An Amish Christmas Journey (Brides of Amish Country Book 12)

Their Holiday Adventure 

Toby Yoder promised to care for his orphaned little sister the rest of her life. After all, the tragedy that took their parents and left her injured was his fault. Now he must make a three-hundred-mile trip from the hospital to the Amish community where they'll settle down. But as they share a hired van with pretty Greta Barkman, an Amish woman with a similar harrowing past, Toby can't bear for the trip to end. Suddenly, there's joy, a rescued cat named Christmas and hope for their journey to continue together forever.
