Captain Stephen Boswell sails under the red flag, a symbol of no mercy. It's the only reason he has lived this long. The only reason the navy has not found him yet. But they are closing in. And if they catch him, they will execute him for piracy. Ten-year-old Alice Bradford doesn't know why she is alive. When Captain Boswell found her hiding on his ship, she expected him to kill her, and it seemed his own crew had expected likewise. But now she is his prisoner and she fears that she will be forever. Somehow, though, it seems that the captain might be more afraid of the navy than she is of him. Something from his past has him ill at ease, Alice realizes. Even if the navy cannot bring him to his knees, his own paranoia will.
