The U-Boat That Vanished
High school seniors Ben Prescott, Porter Rockwell, and Latch McRae don’t seem to fit together at first glance. Homeschooled Ben has brains and vision. Porter is a man of action, with brawn, good humor, and social ability. And Latch McRae is a wizard with engines and equipment. They’re drawn together by a shared passion: treasure hunting for the forgotten loot of American history.
After a hurricane rearranges a sound-side shoreline of the North Carolina Outer Banks, the hunters find a broken piece of antique china on a newly formed sandbar. It’s a shard that comes from the plateware of the WW II German Navy. There’s only one way such a shard could turn up in the sandbank—brought by a sunken enemy U-boat.
But was the German U-boat on the attack, or was it part of a far more mysterious operation? Seeking the answer, the Hunters run up against dangerous local goons and the shadowy, nefarious Alignment, both determined to steal whatever treasure the hunters uncover. Facing long odds, the hunters race for answers, crack old codes that even the World War II codebreaking geniuses couldn’t, and gear up for scuba diving on a dangerous, fascinating wreck that may contain a mountain of wartime German loot, and the answer to a decades-old wartime enigma.
The American Treasure Hunters series is packed with adventure, mystery, and action as Ben, Porter, and Latch search for lost treasure from America’s hidden past.
Book 4 in the American Treasure Hunters series!
“The mystery and the adventure were a lot of fun, but for my money, the best parts were the historical discussions and tidbits sprinkled throughout the book. . . . It’s good. It’s clean. It’s fun. . . . Our heroes are solving a mystery downstream of those facts, and they have to stick to them if they’re going to find the treasure.”—The Federalist
“Andrew M. Dare wants to renew popular culture by directly renewing its seedbed, literature, with stories that will inspire young men to prepare their minds, souls, talents, and imaginations to dream big and achieve big. That’s why he has written a new series of novels for teenage boys who crave adventure and knowledge, learning technical skills and unraveling historical mysteries. Call them Hardy Boys for the Twenty-First Century.”—RealClearBooks.com
“If I’d read it when I was 13 years old, I would have thought it’s one of the greatest books ever written. . . . Ben, Porter, and Latch are fine protagonists, and the story moves along at a fast pace through a well-constructed historical mystery. . . . [The reader gets] a mixture of educational stuff with action, mystery, a little romance (that angle is handled quite well), and a little humor.”—James Reasoner, Rough Edges
“American Treasure Hunters continues to deliver exactly what it promised in Book 1: competent, ambitious young men having old-fashioned adventures while learning real American history. . . . It’s Hardy Boys with modern tech, surfing, football, and podcasts, aimed squarely at boys who want to read about other boys doing cool, heroic stuff.”—Upstream Reviews
