Is this a good starting for a book?

It was cold and all she had was her cloak, t-shirt, and torn jeans. Why did it have to end like this? Karen stopped running and started to walk; almost at a pace of a slow jog. Karen started to see rows after row of houses. Which was now Chrissie’s? The baby started crying as the chill of the wind went by. She wrapped the baby even tighter under her cloak. Out of her pocket she pulled out a piece of paper with four numbers on it, 4975. Is what it read. She scanned the houses for the one with all four digits written neatly on the side of a building. She saw it. She ran holding her baby close to her body as the wind crept up again. Karen ran as she heard her own worse nightmare. “ There is the house,” she thought. They were at the end of a gate. On the other side was a huge house. (It could even be big enough to fit a hundred people in it and still have enough room for it not to be crammed in every corner.) As the gates opened Karen said, “Wow my sister is rich.” Speaking to no one in particular, but it felt good to say something like that at a time like this in her own life. No one was following her. With one of her hands she took off the cloak and with the other she held her baby as tight as ever. She wrapped her baby up in the cloak to keep the chill of the wind out. She placed her daughter down by the doorstep, pulling out another piece of paper. She placed it down next to her baby’s head. With one second in hand, she put a little teddy bear on top. This paper was more important than any address or place in the whole world. This one had fancy cursive writing and lace around every edge of the paper. But it wasn’t what it looked like that was important, but what it contained in the writing itself. Karen started to walk away. As she got closer to the gate she turned her head over her right shoulder to see her baby. One more step and Karen looked back again one more time and whispered to her perfect little angel, “ Good-bye Chrissie,” With hot tears streaming down her cheeks she started running toward the nearby woods, with no cloak to keep her warm. The only word not heard in her whisper was, “forever.” It was now lost in the wind and no one would ever hear that voice again; at least no one that was going to save her in her own nightmares.
