The Mystery of Hidden Harbor, by John Stephen Doherty, by (epub/Kindle/pdf)$2.99
17-year-old Pete Dana runs a boat yard in Hidden Harbor with his father. It's a quiet New England town -- until Jeffrey Fannin arrives. Fannin is reckless and plans to sell a line of red speed boats called Sea Sharks. When Pete makes this mistake of tying up his own boat at what should have been a public dock, it mysteriously comes loose and is almost lost, he suspects Fannin is to blame. And what is Fannin up to at the old factory? Something smells fishy to Pete...and it isn't the ocean! Before he's through, he's going to uncover a mystery that's bigger than anyone in Hidden Harbor ever suspected!
