On Valentine's Day of 2018, Fred Guttenberg rushed his two children, Jaime and Jesse, out the door to school. He had no idea it would be the last time he saw Jaime who was shot and killed later that day in the Parkland School mass shooting. Jaime was murdered just a few months after Fred's brother Michael died of as a result of being exposed to toxic substances when he ran into the World Trade Center as a first responder after the 9/11 attacks.

In his new book, Find the Helpers: What 9/11 and Parkland Taught Me About Recovery, Purpose, and Hope, Fred chronicles his grief, the people who helped him along the way, and his commitment to saving lives by fighting for gun safety.
