Henry and Max have a new stepsister, Peri, and she’s older, nerdy, and bossy. With her nose in a book all the time, Peri has a habit of forgetting everything else—like telling her stepbrothers about a book that just happens to take the three of them back in time. If that isn’t bad enough, Peri doesn’t remember how to get them home.
Each book in the series takes the three children back to a different time in history. Once there, the quest begins. All they need to do is figure out where (and when) they are and what they need to do to get home.
