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.
What began with a reimagining of Peter Pan and Wendy now twists into a stunning version of Alice's Adventures in Wonderland and Through the Looking-Glass! 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 to lead, but things have gotten worse as the cure Doc created for the Horologia virus has mutated, accelerating the disease.
