From "Annabel"'s review on Kirkus Reviews:
" Annabel believes in England’s greatness and the sanctity of the queen. She’s never questioned the status quo. But then her parents are abducted—not even formally arrested—by the police. Suddenly everything changes for Annabel. She is forced to hide with the odd spinster from down the street (Miss Doubtweather) and her nonverbal niece and take flight with a crew of rough-but-kind pirates. Miss Doubtweather, it turns out, is part of a secret society of freethinkers, to which Annabel’s parents also belong. The pirates are more accurately smugglers; breaking the law, yes, but upholding their own moral code. The more Annabel sees, the more she must question her assumptions. But where will this get her? Will Annabel escape the Queen’s Guards and rescue her parents or spend the rest of her days in prison?"
