The Cahill Files: Book 2 is out!
The Cahill Files: Spymasters

In 1814, redcoats burned the White House to the ground. In 1889, Harry Houdini discovered a trick that would save his life. In 1955, the U.S. launched the world's first nuclear submarine. And one family pulled the strings behind the scenes at each of these events: the Cahills -- the most powerful family the world has ever known. Now the Cahills have opened their vault and dangerous secrets are pouring out. This book contains three of them -- three stories that will change history as we know it forever. Flee alongside a young Cahill as Washington burns, unlock Houdini's magic, and stow away with young Fiske Cahill on a desperate mission that could cost him his life.

Venture into the vault if you dare. But don't say we didn't warn you.
