Don Winslow of the Navy #24

When the U.S.S. Barrowsville sinks with the only sample of pentamine—a revolutionary metal for aircraft construction—Navy troubleshooters Don Winslow and Red Pennington race to recover it from the ocean floor. But they're not alone: both Nazi and Japanese forces converge on the wreck, each determined to claim the prize for themselves. Don must use his wits and nerve to outwit the Axis divers in a perilous underwater game where trust is the rarest commodity of all.

Don Winslow lands with the first wave of Marines on Saukan Island to take out enemy barrage balloons—a crucial step to keep the invasion's split-second timetable on track. When the squad hits a minefield while racing to destroy a big gun threatening the operation, the team improvises an audacious solution using captured balloons and sheer ingenuity to reach their target. It's a race against time where Yankee resourcefulness becomes the only weapon that matters.

Don Winslow takes a temporary Coast Guard assignment to investigate why Allied supply ships are mysteriously sinking near an island held by American-friendly natives. Infiltrating a Japanese position on the island under cover of darkness, Don uncovers the secret weapon: camouflaged midget torpedoes launched from native canoes that are nearly impossible to detect. With the enemy ready to strike again, Don and his partner must seize their moment to stop the next attack before another vessel goes down.
