Sixteen-year-old Jack gets drunk and is in the wrong place at the wrong time. He is kidnapped. He escapes, narrowly. The only person he tells is his best friend, Conner. When they arrive in London as planned for summer break, a stranger hands Jack a pair of glasses. Through the lenses, he sees another world called Marbury. There is war in Marbury. It is a desolate and murderous place where Jack is responsible for the survival of two younger boys. Conner is there, too. But he's trying to kill them. Meanwhile, Jack is falling in love with an English girl, and afraid he's losing his mind. Conner tells Jack it's going to be okay. But it's not. Andrew Smith has written his most beautiful and personal novel yet, as he explores the nightmarish outer limits of what trauma can do to our bodies and our minds.
