Glimmer of Hope illustrates how a group of teenagers channeled their rage and sorrow into action and went on to create one of the largest youth-led movements in global history. With personal essays from survivors and a close look at how their collective activism turned conversation into action — via rallies, social media postings, televised town halls, voter registration drives, and ultimately a march on Washington to mobilize for national reform — Glimmer of Hope offers a roadmap for meaningful, youth-led change.
