In the steamy jungles of West Africa, a Marine Reconnaissance platoon races against time to save the lives of American citizens caught in a bloody civil war. One recon team arrives at a mission only to find they are too late. The missionaries had been burned to death while strung up crucifix style. Realizing that the rebels intend to kill all of the missionaries in the region, the Marines race through the jungle in an attempt to beat the rebels to another nearby mission before they can kill the missionaries there. The Marines arrive just in time to see the guerrillas enter the mission compound and begin killing mission workers. The recon team opens fire and the situation escalates. They successfully push the rebels back into the jungle. Gathering the mission workers, including the mission's doctor, Ellen McKenzie, they flee into the jungle. While on the run, the hospital corpsman, Sean Austin, finds himself struggling with his feelings for the young missionary doctor. Traveling day and night they arrive at the platoon's harbor site. While waiting for helicopters to evacuate the Americans to a waiting ship, the group stumbles onto a large underground crypt left by an ancient civilization. A tropical hurricane forces the Americans to take shelter within the crypt; they discover it is actually a portal to another world. Transported to the middle of a lopsided battle, the group is forced to choose sides and fight against a huge medieval army. Once the great battle is over, the reality of this new world leaves the sojourners from earth conflicted and searching for answers about reality, God, and eternity. Sean is particularly conflicted about his life as a prodigal and his attraction to Dr. McKenzie. Into the Breach is a war of ideals, a war between living a good life and living an obedient life. Lliam Morgan takes the reader through adventure after adventure while unraveling our calling, not to be right, but to be obedient.
