Hard return

"Cyril Landry has been a dead man since he escaped a firefight off the coast of Florida three years ago. In all that time, the former Navy Seal has been living off the grid to protect his wife and teenage daughter, who have mourned him and moved on. Five days a week, Landry watches from a distance as his daughter Kristal leaves school. One day a shooter in black unloads his M-16 on the students, killing eight kids- including Kristal's boyfriends, Luke. Landry takes out the gunman with a single sniper shot before melting back into the city. But this wasn't a typical massacre, and the clues add up to only one conclusion: someone knows Landry's alive, and wants him dead- again."-- from book jacket.
