The maze of bones

The Cahill's family matriarch passes away. In her will she leaves one million dollars to each family member, or they can trade that money-order for a clue that will lead to the treasure that will lead them to become the greatest Cahill of all time. There are four branches in the family: Janus, Ekaterina, Lucian and Thomas. Each branch has its own strengths and weaknesses. Our story follows Amy and Dan Cahill, orphans who choose to take the quest. The adventure crosses continents and has clues hidden in art, architecture, music and more.
