"Lockwood & Co. are hired to investigate Edmund Bickerstaff, a Victorian doctor who reportedly tried to communicate with the dead, while Lucy is distracted by urgent whispers coming from the skull in a ghost jar"--

"A terrible crime forces Lockwood to turn to Lucy for help, setting them on the trail of dark secrets at the heart of London society. Both professionally and personally, their investigation stirs up forces they may not be able to control. . . "--

In her diary in 1912, thirteen-year-old Margaret Ann describes how she leaves her lonely life in a London orphanage to become a companion to a wealthy American woman, sails on the Titanic, and experiences its sinking.

Back in London, fifteen-year-old twins Sophie and Josh Newman must determine whom they can and cannot trust as they search for both Scatty and an immortal who can teach Josh the magic of fire, while Doctor Dee and Machiavelli continue to seek power.

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.
