GLIMMER OF HOPE begins on Valentine's Day 2018, shortly after a shooting at Marjory Stoneman Douglas High School in Parkland, Florida, left 17 dead and 17 others injured. Safe at home that evening, junior Cameron Kasky determined "this one has to be different" and that survivors of the shooting, not the media, should be the ones to tell the story. Two days later, he and a group of close friends met in his living room and began an extraordinary five-week journey that would see student activists from Marjory Stoneman Douglas organize March for Our Lives, a demonstration in support of tighter gun control that drew 800,000 participants to Washington, D.C. The following chapters, each written by organizers or participants in the march, show how students put together a social media team and organized trips to Tallahassee and Washington, D.C., to speak with lawmakers (Senators Lindsey Graham, Paul Ryan, Nancy Pelosi, Chuck Schumer, Bill Nelson, Bernie Sanders) about gun reform. Many of these meetings would prove demoralizing, as the students felt they never got straight answers to their concerns and questions. Organizers write about doing interviews with major media outlets, speaking at an anti-gun rally three days after the shooting, and participating in a CNN Town Hall, where they confronted Sen. Marco Rubio about taking money from the NRA. Numerous students recall heartbreaking memories in the "First Day Back at School" chapter, where they were welcomed by therapy dogs and police officers carrying the same weapon the shooter had used. "The March for Our Lives" chapter includes both reflections from participants and excerpts from speeches given by several students. The book ends with a look at what the future holds for the organizers of the march, a new movement called Road to Change, whose goal is to educate, register, and motivate young people to vote.
