Emil was raised as a boy, partly because this is medieval Europe (and you could get away with that sort of thing back then) and partly to protect her after the murder of her family. Now, guided by the voice of the late Joan of Arc, Emil goes off to fight in the Hundred Years War. It’s an age-old question — if God started talking to you, would you answer the call? — and Joan Book I (two more installments follow) tackles it with a mature, deft sensitivity that’s amplified by writer-artist Yoshikazu Yasuhiko’s soft, delicate painted artwork. It’s like Joan of Arcadia but, you know, in France, with horses.
