The Far Reaches (2007) [JOSH THURLOW #3]

The year is 1943 and World War II in the Pacific rages on, with Americans engaged in desperate battles against a cunning enemy. Coast Guard Captain Josh Thurlow is on hand at the invasion of Tarawa, as the U.S. Navy begins the grand strategy of throwing her marines at island after bloody island across the Pacific. But nothing goes as planned as young Americans go up against fanatical defenders, who revel in snipers, big guns, and human wave attacks from which there is no escape save death. 

As blood colors the waters around Tarawa, Josh flounders ashore through a floating graveyard of dead men and joins the survivors, determined to somehow wrest victory from disaster. Critically wounded, ,Josh expects to die. Instead, he is spun off on one of his greatest adventures when Sister Mary Kathleen, a young Irish nun, nurses him back to health, then shanghais Josh, sidekick Bosun Ready O'Neal, and three American marines to a group of beautiful tropical islands...
