In her first book for young adults, McDonald (Project Girl, for adults) uses a chorus of highly authentic, lively young voices to convey heartbreaks and dreams reverberating in a Brooklyn ghetto. From the outside, Raven appears to be just another "housing project girl," whose prospects are as bleak as those of her best friend, Aisha. Both teens are high school dropouts, unwed mothers and virtually unemployable but, unlike Aisha, Raven is not content to rely on "the system" for support. Her chance to gain independence and to carve out a better life for herself and her son comes in the form of a spelling bee. If Raven wins the contest, she will be able to enter a college prep program, then go on to college on a full scholarship. Offering balanced portions of humor and drama, the novel traces how Raven gradually gains confidence in herself and her future as she prepares for the spelling bee. McDonald paints Raven's path to success as realistically rocky, obstructed by such complications as the reappearance of her baby's father and the disturbing news that Aisha is pregnant again. If the story's resolutions seem a little too pat, the heroine's passionate determination remains admirable. Her ability to turn her life around defies the notion that girls like her and Aisha are stuck on a dead-end street. Ages 12-up. (Oct.)
