The Harmony Scroll - Book 2 of the Peacetaker Series, #2

One curse that must be lifted if humanity is to survive.... Carter tries to convince Dr. Hunter that history is full of clues that lead nowhere. Especially such tales as thousand years old hearsay about a treasure ship that sunk in a storm. And while the history professor in Stella might be inclined to agree and turn her back on such tall tales, the mother in her can't. Not when the life of her son depends on it.
