The headlong magical adventure begun in The Alchemyst (2007) shifts from California to Paris. There the gifted but untrained twins Josh and Sophie meet a further array of immortal friends and foes—“human, inhuman, and abhuman”—from history and legend, including but not limited to Joan of Arc, Niccolo Machiavelli, valkyries, the giant reptilian Nidhogg and all of the gargoyles and grotesques of Notre Dame brought to life. Though Scott’s efforts to blur the line between Bad Guys and Good seem occasionally labored (particularly Josh’s stubborn suspicions about Flamel’s motives in the face of continual evidence to the contrary), readers will be swept up by a plot that moves smartly along, leaving a wide trail of destruction and well-timed revelations. Uncharacteristic in a middle volume, things are looking up at the end for the twins: Sophie has learned Fire Magic, Josh’s powers are Awakened at last (though at an ominously unspecified price) and back in California Flamel’s brilliant wife Pernelle has escaped imprisonment. Stay tuned. (Fantasy. 11-13)
