As the only child of a widowed bookseller in 17th century London, twelve-year-old Meg Moore stands to inheirit her father's entire estate. Because she is an heiress, Meg will be able to take part in the bookselling trade - her greatest wish - and will be able to chose her own husband. But Meg's entire future is changed when her father decides to remarry. Meg dislikes her new stepmother, Susannah, even though Susannah tries to be kind to her. She fears that Susannah will provide her father with a son that will take Meg's place as his heir, and that she will be reduced to marrying any man that will take her, or even worse, working as a maid. But over a year of change, Meg realizes that accepting Susannah can only bring good, and that there are ways that she can help influence her future, even if she is not an heiress. This was a fascinating glimpse into a time period that is not often written about in young adult fiction. Highly recommended.
