Emily Adrian’s young adult book “Like It Never Happened” centers on Rebecca Rivers, a high school girl who gets the lead in her school’s production of “The Crucible.” She manages complicated relationships with her four castmates, referred to as “The Essential Five,” while devoting herself fully to the play. Rebecca can’t help but be pulled to her attractive co-star Charlie Lamb, even though they have promised not to date. However, a life-altering charge that has the potential to ruin everything eclipses their on-and off-stage drama.
