“ Sometimes, Arin almost understood what Kestrel had done. Even now, as he felt the drift of the boat and didn't fight its pull, Arin remembered the yearning in Kestrel's face whatever she'd mentioned her father. Like a homesickness. Arin had wanted to shake it out of her. Especially during those early months when she had owned him. He had wanted to force her to see her father for what he was. He had wanted her to acknowledge what she was, how she was wrong, how she shouldn't long for her father's love. It was soacked in blood. Didn't she see that? How could she not?Once, he'd hated her for it. Then it had somehow touched him. He knew it himself. He, too, wanted what he shouldn't. He, too, felt the heart chooses its own home and refuses reason. Not here, he'd tried to say. Not this. Not mine. Never. But he had felt the same sickness.In retrospect, Kestrel's role in the taking of the eastern plains was predictable. Sometimes he damned her for currying favor with the emperor, or blamed her playing war like a game just because she could. Yet he thought he knew the truth of her reasons. She'd done it for her father. It almost made sense. At least, it did when he was near sleep and his mind was quiet, and it was harder to help what entered. Right before sleep, he came close to understanding. But he was awake now. ”
