Grade 6–9—In this conclusion to the series, Charlotte and her mild-mannered English cousin, Zee, continue to go toe-to-toe with threatening gods, goddesses, and a menagerie of mythological serpents, nymphs, and demons. This novel begins after a pleasant family cruise runs amok and a surly Poseidon jettisons Charlotte halfway around the world, and she is compelled to face off against tumultuous and arrogant gods. This time, tsunamis, natural disasters, and monsters from Hades are destroying the world. Fate steers the cousins to Olympus to have a serious chat with Zeus, restore Earth to order, and save all of humanity. And Charlotte thought seventh-grade math was rough! The action rarely stops, gathers momentum, and goes extreme. Following the 13-year-old cousins as they duck in and out of trouble is half the fun; meeting the irascible and complicated cast of Olympian characters is the rest. From a cameo appearance of Apollo roller-skating around the crystal decadence of Olympus to the girls' eventual confrontation with a thunderously lusty but mostly ineffectual Zeus, the humor is raw and rich. Complementing the story's action, and tempering the humor, is the reappearance of the demonic Philonecron, Poseidon's psychotic grandson. He lurks and schemes in the shadows, creating ever more tension. The young mortals right the immoral wrongs of the gods, but it's the deft blend of intricate plot development, flippant tone, and a fresh twist on an ancient theme that gives this novel its winning finish.—

The evil Philonecron survives the cousins’ great battle with Poseidon (The Siren Song, 2007), albeit ignominiously, in the stomach of a great sea monster. When said monster meets an unfortunate end, Philonecron finds himself free and in possession of another digestive artifact: Poseidon’s trident. He promptly sets off to conquer Mount Olympus, while Charlotte and Zee attempt to save all with another object of great power: the eternal Promethean Flame. A veritable kitchen sink of mythology and relentlessly action-packed, this third book in the series will be a satisfying addition to its predecessors, but will not stand easily alone.
