Ted Jacobs, a young staff physician on duty in the ER of a regional hospital in Laramie, Wyoming, has heard some strange stories in his time. But when a dying Native American gunshot victim tells of being wounded by white settlers in wagons and having to escape a pack of wolves by crawling through a spirit opening in the back of a cave, Ted's instincts lead him to look for that opening. With the help of fellow members of a local spelunkers club, Ted goes in search of the mysterious opening. Their search takes them through a time portal to the early nineteenth century on the Oregon Trail, where they are vital to the survival of three adolescents. Based on a story partially written by his mother that was discovered after her death, author John Morton skillfully weaves a time-shifting adventure with genuine human emotion that will fulfill readers young and old. John Morton is a semi-retired engineer in the power generation industry. He lives in a rural area on the Cumberland Plateau in East Tennessee with several children and grandchildren nearby.
