It is 1794, and the Reign of Terror is at its height. Having disposed of many of the aristocrats, the people have turned on each other, and anyone who ever served an aristo is in danger. Yann Margoza is working with a group of trusted friends as a masked magician in the most popular show in Paris. Everyone knows him as the Harlequin, but this is just a cover for his true mission. With the help of Didier, his trusted friend, and the threads of light, he is smuggling people out of Paris to safety, sometimes right under the noses of their jailers.
Sido is in London living with the Laxtons, her aunt and uncle, but only Henry Laxton knows what Yann is doing because he is part of the network. Juliette Laxton knows Sido is in love with Yann, but she cannot condone this love between her beautiful aristocratic neice and a gypsy who gave up his future to be an actor. Despite each new revelation about Yann, Sido is devoted to him and longs to see him again.
Sido and Yann saw Count Kalliovski die in the September Massacre, but perhaps Tetu is right, and the evil Count really was saved by the devil. Now the lovers are both in danger from the Count's dark magic world hidden beneath the streets of Paris in catacombs filled with human bones.
This sequel to "The Red Necklace" is one part Scarlet Pimpernel, one part Dickens, and one part Harry Potter. Though the story is not as intricate and well-structured as "The Red Necklace," this book is fast paced, exciting, and romantic. Fans of the first book will be satisfied!
