Survival at the Oasis [EPUB ebook] 

When Daljan is placed in charge of a team of skilled sailors, on a top-secret mission to fly into a foreign country yet to have been announced, somewhere over the Pacific Ocean their airplane runs into trouble and is forced to crash land on a desolate island. After months, the remaining survivors are able to scrounge parts from the airplane and old-World War II vehicles left on the island after the war. With a combined effort of the men, they hope to build a boat and sail off the island to freedom.
