Humanity’s at risk – again – and we need a special kind of secret agent to save our collective arses . . . so step up Eddie Drood!During World War II, the Droods made a pact with some nasty buggers from another dimension known as the Loathly Ones, in order to defeat the Nazis. But once the war was won and the pact was fulfilled, the Loathly Ones decided that they liked this world too much to leave, and the Droods are the only thing stopping them from world domination.Unfortunately, it seems that Eddie may not be able to trust every member of his family, and if he chooses the wrong horse to back, everything he – and the rest of humanity – holds dear will go up in smoke.Daemons are Forever is the second book in the Secret History series from the New York Times bestselling author of The Man with the Golden Torc.
