Title character

Plot summary
Nicholas Flamel, Perenelle Flamel, Sophie, and Josh return to San Francisco. The Flamels go to their book store while Josh and Sophie head for their Aunt Agnes' house. When they approach they see a limousine waiting outside and a stranger talking to their Aunt. They approach with caution but in the following scuffle on the doorstep Sophie is dragged into the car by a female looking exactly like their lost friend Scathach, but who is in fact her twin, Aoife. Josh races to the book store to alert Nicholas and Perry and together, they set out to rescue Sophie who has been taken to a houseboat in Sausalito owned by Aoife's companion, the Japanese immortal, Niten.

Dr. Dee has been declared utlaga (a wanted man) for his failure to capture the missing pages of the Codex by his Dark Elder masters. Not wanting to experience their wrath, he flees. He makes his way across England from Salisbury Plain to his London office with the last two legendary swords, now fused together, in his possession. Once in London he enlists the help of an old acquaintance, Virginia Dare, and after an encounter with some cucubuth bounty hunters the pair escape to Dee's home in San Francisco, where he prepares to call back the Archon Coatlicue – the Mother of the Gods – to help him with his plans to conquer planet Earth and take revenge on The Dark Elders that made him an outlaw.

Joan of Arc and Scathach are joined in their exile by William Shakespeare, Palamedes and the Comte de Saint-Germain after they seek out Lord Tammuz's help. Shortly after they are reunited they are joined by the mysterious, hooded, hook-handed man who tells them that he has a pre-destined mission for them. He takes them through Xibalba and several other shadow realms to the Earth over ten thousands years ago, when Danu Talis still existed and they have to fight in the battle that meant its downfall.

Niccolò Machiavelli and Billy the Kid get off the monster filled Alcatraz Island with the help of Billy's Dark Elder Master who sends the immortal Black Hawk to retrieve them and bring them both back to his house. After a fraught meeting with Billy's master they count themselves lucky to be alive as they had failed to accomplish the missions given to them by their masters: to kill Perenelle and to set loose the monsters trapped on the island onto San Francisco. The pair set out to return to Alcatraz and make amends by achieving what they were tasked with doing.

After their initially tense meeting, Aoife, Niten, Josh, Sophie, Nicholas, and Perenelle agree to travel to Point Reyes so that Josh can be taught the magic of fire by Prometheus, the Master of Fire. Josh is separated from the others shortly after learning the magic of fire and finds himself walking into Dee's home, Sophie wakes up and realizes that Josh is missing. After alerting the others about his disappearance they track Josh to Dee's home. Sophie, Aoife and Niten race to stop him from unwittingly helping Dee complete his plan to summon the fearsome Coatlicue who Dee plans to turn loose on the Dark Elders, while Nicholas and Perenelle stay with Prometheus, following what they do. Josh, still under enchantment, turns against his sister and escapes with Dr. Dee and Virginia Dare, while Aoife pushes Coatlicue back into the shadowrealm it came from, but leaving herself trapped with it. This leaves the end of the book on a cliff hanger. The Flamels are very weak, the twins are divided, and the Dark Elders are gathering in anticipation of the Final Summoning at Litha, when they hope to return to power and dominate the world
