12th of Never - James Patterson

It's finally time! Detective Lindsay Boxer is in labor-while two killers are on the loose.
Lindsay Boxer's beautiful baby is born! But after only a week at home with her new daughter, Lindsay is forced to return to work to face two of the biggest cases of her career.
A rising star football player for the San Francisco 49ers is the prime suspect in a grisly murder. At the same time, Lindsay is confronted with the strangest story she's ever heard: An eccentric English professor has been having vivid nightmares about a violent murder and he's convinced is real. Lindsay doesn't believe him, but then a shooting is called in-and it fits the professor's description to the last detail.
Lindsay doesn't have much time to stop a terrifying future from unfolding. But all the crimes in the world seem like nothing when Lindsay is suddenly faced with the possibility of the most devastating loss of her life.
