All good stories make their readers regret reaching the last page. However, the best stories produce daydreams about their characters long after the last page is turned; daydreams about how these imaginary companions would behave if placed in fantasies created in a reader's head. "An Exchange of Hostages" presents a conundrum to its readers. Why? Because this story will make its readers delight and revel in the character development and training of a professional torturor and will then make the reader want more. Susan Matthews has managed to create a bizarre "coming of age" novel about a young surgeon forced by the dictates of family honor and pride to serve in an intergalactic military fleet which has more need for his skill in inflicting pain rather than his skill in alleviating it. This novel examines pain in depth; the mental pain of the one learning to enjoy inflicting pain and the physical pain of the one who must submit to it. Like Dante's Inferno, the reader is taken one level at a time towards more and more extreme acts of controlled violence until a horrendous destination within the human psyche is reached. Matthews guides each step with an unerring eye upon the delicate balance between fascination and revulsion. Her main character, Andrej Koscuisko, is as introspective as any Russian character in any Russian play and Matthews pulled no punches when she wrote of his physical and mental reactions to his admittedly vile training. She has managed to keep the character sympathetic by juxtaposing his reactions to the even viler reactions of those undergoing the same training. The end of the novel coincides with the end of his training and leaves the reader wondering how young Koscuisko will make use of his newfound talents in the big, wide, nasty universe. This reader hopes that Matthews' second novel will be just as disturbing as the first, even though there was a tinge of self disgust present for enjoying the first novel so much.
