A teacher who helped save the lives of students at Sandy Hook Elementary School on 12/14 has a book deal.

G.P. Putnam's Sons announced Tuesday, July 29, that Choosing Hope: Moving Forward from Your Life's Darkest Hour by Kaitlin Roig-DeBellis will be released next spring. The publisher says the book will be a "poignant account of personal triumph over unbearable tragedy." Robin Gaby Fisher is co-writing it.

Roig-DeBellis hurried 15 first-graders into a bathroom upon hearing gunfire at the school on December 14, 2012, saving their lives. The gunman eventually shot himself to death after gunning down his mother, six teachers and 20 children.

Last year, Roig-DeBellis founded Classes 4 Classes, a nonprofit that advocates teaching children that all lives are connected.
