Forced apart by the Great Equestrian War, Carter writes love letters to his marefriend, Amily, who lives in Trottingham. She never writes properly back to him, instead sending a small gift and short note. They grow more and more distant every day, even though they both love each other. But when Carter discovers the secret that makes Amily almost unresponsive, he travels back to Trottingham-and discovers an even more shocking secret.
