Si c'était à refaire

"On the morning of July 9, 2012, New York Times investigative reporter Andrew Stilman is jogging alongside the Hudson River when he feels a sudden, sharp pain in his lower back. He collapses in a pool of blood. When he regains consciousness, it's May 7--two months earlier. Stilman now has only sixty days to find out who wants him dead and why until his killer finds him again."--Jacket flap.
