Hippolyta and the Curse of the Amazons — Jane Yolen; Robert J. Harris

Before she became Queen of the Amazons, young Hippolyta fought to break a goddess's curse...

An ancient prophecy states that any Amazon who bears two sons must kill the second, lest he grow up to destroy all the Amazons. But Queen Otrere can't bear to sacrifice her baby, so she gives him to her daughter, thirteen-year-old Hippolyta, begging her to take the child to his father, Laomedon, King of Troy. In order to save her baby brother's life, Hippolyta must find a lost city and lift a goddess's curse. Along the way, she will need help from an unexpected source: a newly discovered brother. But can Hippolyta bring herself to trust a boy in order to save the Amazons?
