Review"YOU ARE INVITED TO THE MINOR HIGH SCHOOL CLASS OF 1979 REUNION... BE THERE OR BE SQUARE." When Claire Montrose first reads the invitation, she reacts with a grimace (who wouldn't?) . But while some things have changed since 1979, Claire, the curious, self-conscious heroine of April Henry's previous Circles of Confusion and Square in the Face, is still tall, thin, smart, and young-looking for her years. Deciding to flaunt the traits that kept her low on the high school social pecking order 20 years ago--and also show off her gorgeous Manhattan art curator boyfriend, Dante--Claire sends in her acceptance.. But the reunion weekend's first mystery crops up when Claire and Dante check in at Ye Olde Pioneer Village. Someone has left Claire a little heart-shaped box with a picture of her teenage self inside. And the first few drinks of the reunion icebreaker party have barely been downed when Cindy Sanchez, former head cheerleader and Minor High good-time girl, is found strangled in the parking lot, with another heart-shaped box in her hand.
