Gr 7-10 Riva Lightman, 15, lives a poor but happy life with her parents in Brooklyn. Riva's mother, however, wants Riva to experience life with wealth and privilege. She arranges for Riva to spend a month with a rich Park Avenue lawyer, Herbert, whose marriage proposal she had rejected to marry Riva's father; his wife, Ava; and daughter, Caroline. Naturally, Caroline is spoiled and unhappy; Ava is vain and cold; Herbert is withdrawn and asthmatic; and the cook and even the dog are hostile. And , Indian prince/student Ravi lives in the spare room, but is mysteriously invisible. Ravi makes a play for Riva (cosmic name similarity), taking her to the same elegant restaurant in which Herbert proposed to Riva's mother and where Ravi and Riva ridiculously replay the scene. But the romance is doomed: Ravi is also having an affair with Ava. The plot is predictable, the characters transparent and unremarkable. The theme of rich but miserable, poor but happy is shamelessly heavy-handed. Ellen Ramsay, Amphitheater High School, Tucson, Ariz.
