Historical fantasist Graham (Black Ships
) heads to Egypt with this elegant, engaging memoir of Charmian, half-sister and handmaiden to Cleopatra. The two young women and their other sister, Iras, are inseparable from childhood, getting one another into and out of numerous mishaps. As teenagers, they vow to Isis that they will protect Egypt from the covetous Romans, and in return for their devotion, the goddess rewards Cleopatra with the throne. Graham never resorts to melodrama even at the murder of Julius Caesar or to cliché when Charmian recalls her past lives, and she supplies plenty of superb historical detail, but doesn't let it overwhelm the narrative. Charmian's shy hopes, failures and devotion to Cleopatra and Isis make her one of the most memorable “witnesses to history” to emerge from fantasy in quite some time. (Apr.)
