Booker chuckled softly. Andy with single word responses was a very good sign she was about to drift off. This was what she wanted, after all, when she climbed into bed with him.

He was her living heated blanket and her soothing white noise. That was fine with Booker. He felt a real sense of satisfaction being able to help like this. It was one little way he could help and something he was good at.

So, Booker started humming an old lullaby under his breath. He didn't want to bother the others sleeping nearby. It was just to put Andy that last little bit over the edge into sleep.
