Cleopatra's Moon by Vicky Alvear Shecter (Published by Scholastic, August 1, 2011)
Selene has grown up in a palace on the Nile with her parents, Cleopatra & Mark Antony--the most brilliant, powerful rulers on earth. But the jealous Roman Emperor Octavianus wants Egypt for himself, & when war finally comes, Selene faces the loss of all she's ever loved. Forced to build a new life in Octavianus's household in Rome, she finds herself torn between two young men and two possible destinies--until she reaches out to claim her own.
This stunning novel brings to life the personalities & passions of one of the greatest dramas in history, & offers a wonderful new heroine in Selene.
This sounds like such a great topic for a YA historical. I have read several books on Cleopatra and enjoyed them, so I am looking forward to reading for the first time a novel about her daughter, who sounds like she had a very interesting life!
