London has been destroyed in a blitz of bombs and disease. The only ones who have survived are children, among them Gwen Darling and her siblings, Joanna and Mikey. They spend their nights scavenging and their days avoiding the ruthless Marauders -- the German army led by Captain Hanz Otto Oswald Kretschmer. Unsure if the virus has spread past England's borders but desperate to leave, Captain Hook hunts for a cure, which he thinks can be found in one of the survivors. He and his Marauders stalk the streets snatching children for experimentation. None ever return. Until the day they grab Joanna. As Gwen sets out to save her, she meets a daredevil boy named Pete. Pete offers the assistance of his gang of Lost Boys and the fierce sharpshooter Bella, who have all been living in a city hidden underground. But in a place where help has a steep price and every promise is bound by blood, it will cost Gwen. And are she, Pete, the Lost Boys, and Bella enough to outsmart Captain Hook?
Gwen, Pete, and the others have escaped from Everland. But the safe haven they hoped to find at Alnwick Castle doesn't exist. With the Queen of England on her deathbed, Duchess Alyssa has stepped in, but things have gotten worse as the cure Doc created for the Horologia virus has mutated, accelerating the disease. The only possible solution he can think of is to go back to the virus's origin: an extinct poisonous apple.Legend has it a tree bearing the apple might be found at the center of a deadly labyrinth hidden deep within Germany. A place that no one in their right mind enters. With no other options, Alyssa sets out with only her sword, her wits, and the help of Maddox Hadder, a wild boy who oversees the castle gardens. To get to the center of the maze, she'll be forced to battle monsters more terrifying than her darkest nightmares.But can anyone truly survive the madness of the maze? And what if there's no apple to be found there?
