High school reunions are often a tempest of emotions and unresolved issues, but what if it was your first reunion in 45 years? That's the question posed by Elizabeth Berg's new novel The Last Time I Saw You, where everyone from the class beauty to the class outcast, as their old personalities emerge and decisions are made that will affect the rest of their lives. Berg will also appear at the Regulator Bookshop at 7 p.m. on May 20. —Zack Smith
