Evan Hansen, a teen crippled by anxiety, starts each day by writing a letter of encouragement to himself. When loner Connor Murphy finds one of the letters at school and dies by suicide days later, his parents deliver the "Dear Evan Hansen" to Evan, who lies about being Connor's best friend. As the Murphys embrace Evan, his lie goes viral, giving comfort to the grieving family and making him a social media darling. But as the lies build, Evan's guilt forces him to admit the truth. In this stage-to-page adaptation, characters' back stories offer depth only hinted at by the Tony Award-winning musical.
