Clever and creative, and funny. "Sometimes being rich helps. Sometimes it doesn't." I like that there's a distinction made between being a detective, an agent for secrets, and a spy. I like that nothing is ever as easy as it seems at first, but Olivia persists.

Best if read in order, but not necessary. I wish there were more.

(same review for each)

Silly and fun…

I'm not native, but I can read it easily. It's a simple and cute story so I enjoy reading it.

Olivia Sharp is Nate the Great's cousin and like him, she loves solving mysteries. She even has an entire room in her house dedicated to working on her cases and having hotline phones for clients who need help. Her first client, Duncan, has lost his best friend. Can Olivia help him?

I enjoyed Olivia's process in solving this "mystery" and the lessons she learns through the mistakes she makes. I also liked how the mystery was really about friendship and relating to people.

An engaging picture book for beginning readers. Mystery component gets them hooked and opens a series of future titles to read. Olivia and Duncan offer great characters for a study in characterization.

I did not like this book because I don't really like pizza anymore. I also did not like this book because I do not like boring calls from other people.

I love this series!!!!!!! Olivia Sharp is the best!!!

I liked this book because it was a mystery of trying to help somebody get back his friend. I also liked this book because all the ideas she tried out was about pizza.

Our girls (especially our youngest) love the Nate the Great books by Marjorie Weinman Sharmat. And we enjoyed the somewhat bizarre tales when he interacts with his cousin, Olivia, like Nate the Great Talks Turkey and Nate the Great, San Francisco Detective, and Nate the Great on the Owl Express. So we thought we'd check out this series, too.

Overall, I liked this story better than The Princess of the Fillmore Street School, but I still wasn't terribly impressed with it. I thought it was nice that she helped a young boy discover a sense of humor. Our girls liked it, and as we're almost to the end of the Nate the Great books, I was glad there was another series with a (tenuous) connection to Nate. I still get annoyed that Olivia is as rich as Eloise, but older and with more cash at her disposal. We've finished the four book series now and although our girls liked these stories, I'm glad there are only four in the series.

Boys and girls are different. Girls don't think it's endearing to tell them their food looks disgusting. Boys don't understand why girls have a problem with that.

Not a lot of depth of plot at all. Pretty unrealistic that she has a ton of money and could do whatever she wants...
