Dominion, written by C.J. Sansom, is a gripping alternative history mystery set in a world where Britain surrendered to Nazi Germany during World War II. The story takes place in 1952, with Britain under Nazi rule and resistance movements brewing in the shadows. Against this backdrop, a civil servant named David Fitzgerald becomes embroiled in a murder investigation that uncovers a dangerous conspiracy. Sansom's meticulous attention to historical detail and his skillful blending of mystery and alternative history make Dominion a compelling read for fans of both genres.
