The Agents of the Crown-the "rollicking new historical thriller" (The New York Times Book Review) series-returns with this riveting novel following the original MI6 agent as he is assigned a dangerous mission to recreate a weapon from antiquity. As she travels through Waltham Forest, Queen Elizabeth I is ambushed by masked gunmen who leave her carriage riddled with holes before disappearing into the night. The Queen's Private Secretary, Sir Francis...

While working at pleasant but mundane summer jobs in San Francisco, fifteen-year-old twins, Sophie and Josh, suddenly find themselves caught up in the deadly, centuries-old struggle between rival alchemists, Nicholas Flamel and John Dee, over the possession of an ancient and powerful book holding the secret formulas for alchemy and everlasting life.

Fifteen-year-old Josh has chosen to side neither with his twin sister Sophie nor with the Alchemyst, Nicholas Flamel, but rather to fight alongside Dr. John Dee and the mysterious Virginia Dare, while the immortal Machiavelli and Billy the Kid follow the Elders' plans to set loose the monsters of Alcatraz on San Francisco and trigger the end of the humani race.
