She had decided she wasn’t angry that Peter had left without telling her. She had been at first, when Hollis came to the mess to give her the news; but with Sancho and Withers to take care of, she hadn’t dwelt on these feelings for long. And the truth was, she’d sensed it coming—if not Peter’s and Amy’s departure exactly, then something like it. Something final. When she and Hollis had discussed leaving with the convoy, always in the background, unstated, was the feeling that Peter and Amy wouldn’t be going with them.

But Michael had been angry. More than angry—furious. Hollis had practically had to restrain him from heading off after the two of them, into the snow. Strange how Michael had become so brave, almost recklessly so, over the months. She had always felt herself to be a kind of stand-in parent, responsible for him in some deep, incontrovertible way. Somewhere along the way, she had let these feelings go. So maybe it wasn’t Michael who had changed; perhaps it was she herself.
