I like the plot of Haven. It caught my attention and was easy to understand. I couldn't put the book down! I like how it gave Queen Gabrielle some part of the action. In the other books in this series, she doesn't have as big of a role in the action as she does in Haven. I like Queen Gabrielle. She makes the story better when she is funny and smart, especially when she finds out who kidnaped the twins. I do wish the author focused more on Olive. I wanted to know more about what happened to her. I missed having her as the main character as she was in the first book. This book is an excellent example of courage and bravery. It has more action than the other books in the series. Readers should read the first three before this one to understand what is happening. I recommend this book series to anyone over twelve who is looking for action books.
