The Rapscallion Club (The Rapscallion Club: Book One)

What do French fry contests, bullet ants, and the lost art of umbrella combat have in common with dead pirates, island treasure and an excoriated Titanic survivor named Sir Cosmo Duff Gordon? A ten year old boy from New Jersey finds out when he travels to Peru by way of an underground tunnel that magically connects the cellar of his house to the basement of the South American Explorers Club, an eccentric and possibly haunted establishment chock-a-block with bones, stones, tusks and teeth.
